CPU Hot Plugging
[edit]Linux supports CPU hot plugging, but the article claims that CPUs are only cold swappable. See https://events.static.linuxfound.org/sites/events/files/lcjpcojp13_fenghua.pdf for explanation of CPU hot plugging. — Preceding unsigned comment added by 155.41.22.94 (talk) 15:25, 14 May 2018 (UTC)
Clarification required
[edit]The Blade server article says Blade servers are ideal for specific purposes such as web hosting and cluster computing. Individual blades are typically hot-swappable, which doesn't appear to fit with the hot swap versus plug distinction (interaction with software) in this article. Also, the article is talking about components of a computer whereas a blade server is a computer component of a cluster of computers.78.146.78.223 (talk) 12:51, 31 October 2008 (UTC)
Hot Swap vs Hot Swapping
[edit]Somehow a names needs to be chosen and hot swap and hot swapping need to be combined. Kail Ceannai 21:52, 2005 May 12 (UTC)
- Hello? Merge anyone? 193.1.100.102 11:35, 18 August 2005 (UTC)
- Kail, both of your links go to the same article, so, in effect, the two terms are already combined. --John R. Sellers 04:59, 24 August 2006 (UTC)
PS/2
[edit]It says PS/2 is not hot-swappable, but this is not true. I can hot-swap my keyboard and mouse on my Linux box. 70.52.147.11 00:14, 22 March 2007 (UTC)
- Although rare, hotswapping PS/2 mice/keyboards may damage motherboard, most likely by blowing the fuse in-line with the power pin on the PS/2 connector. Having said that, I've also hot-plugged keyboards and mice before with no trouble. Sagsaw 19:16, 14 April 2007 (UTC)
Firewire: Cold or Hot?
[edit]In the section where true hotswappable and hotswappable where the OS must be notified by the user are compared, FireWire is used as an example of both types. Does anyone know which side is the correct one to place FireWire? I guess it should be on the "hot" side, as USB, but I'm not sure.
- Afaict with both USB and firewire nothing bad will happen on a bus level if you just pull it out. However higher level stuff may not be ready if it isn't warned (for example with a hard drive the OS may still have data cached). Plugwash (talk) 02:17, 13 January 2009 (UTC)
IDE hot swap bays?
[edit]I was looking for information on how these work: are they reliable, do they slow down the drive? It would be great if someone who knows about this filled in some info on these devices. I know pretty much nothing about it, so I won't even try to mention them.
Damage
[edit]There are two aspects here: one is whether the device(s) break, and the other is whether they work. Devices that are not designed to hot swap may permanently break if plugged or unplugged while powered (example: PS/2). Devices that are designed to hot swap generally have hardware and software aspects. The user can assume that plugging and unplugged while powered will not break them. (Example: USB) But whether they will instantly, automatically "just work" all depends on many factors -- YMMV. -69.87.204.161 01:00, 19 March 2007 (UTC)
Component Shutdown and Redundancy
[edit]The sentence: "More complex implementations may recommend that the component be shut down, but there is sufficient redundancy in the system such that if a component is removed without being shut down, operation continues."
This seems a bit confusing to me however I want to avoid altering the meaning by changing the sentence structure. Does the following sound OK?
"Whilst more complex implementations may recommend that the component be shut down, there is usually sufficient redundancy to allow operation to continue uninterrupted while the component is taken offline." Sardaukar86 22:38, 13 November 2007 (UTC)
- I don't think it is quite the point being made. I think the point is that if you have hot standby type configurations then although there may be a proper way to nicely swap over, the fail over mechanism should allow for an abrupt changeover. I'd quite like to see some source examples, as this is an important point. On a SAN, you have hot standby disks and you can go through a management procedure to implement the standby disk, swapping the offline disk without the need to shutdown the SAN. If you take out the broken but active disk without first taking it out of the set, would the system survive? (Answer: I don't know and I wouldn't try it!). Spenny 09:52, 14 November 2007 (UTC)
Removed cleanup tag, added refs tag
[edit]I changed some minor parts of the article, I think it no longer deserves the cleanup tag. However, as there are hardly any refs (I added the only one), i included the refimprove tag. Anyone who has some good sources on this field should look into this, the article seems solid otherwise Meertn (talk) 11:16, 25 December 2008 (UTC)
What means hot plugging?
[edit]Its not fully answered in the article introduction although hot plugging is redirected to this article --demus wiesbaden (talk) 00:11, 10 March 2009 (UTC)
Hot pluggable SATA/eSATA
[edit]I posted a question on hot swapping at Talk:Serial ATA:
Something that's not obvious from this article or the article on hot swapping... maybe someone can comment here, find cites, or update the articles with useful information. SATA itself by design is hot swappable, and yet there is minimal to no clear answer in these articles as to when and under what conditions a user can actually use that capability. For example:
- Under which operating systems?
- Which kinds of drivers, BIOS features, or specialized bridge/interface chips or cards are required?
- To what extent is effective hot swappability available in mainstream PCs using a SATA hard drive?
- Does unplugging or connecting a SATA drive to a modern power supply cause transients that may crash or harm the system? if so how does one power an external SATA drive (hot swapped or otherwise)?
A comprehensive answer (either here or added to the article) would be useful, thanks.

PS/2 mouse
[edit]How to make XP recognise a hotplugged PS/2 mouse ? It does not detect it. I also tried the "Scan for new Hardware" option in Device Manager, but no results.

Merge
[edit]Maybe this should be merged into hot swapping? I've only been able to find three usable references. I also removed part of the lead that was copied from page 20 of LPI Linux Certification in a Nutshell. Feezo (send a signal | watch the sky) 09:55, 5 June 2011 (UTC)
- Support this article is just a smaller copy of the hot swapping article. CJ Drop me a line! • Contribs 18:15, 9 October 2011 (UTC)
Done. The coldplug article has now been merged into the hot swapping article.
Still needs some post-merge cleanup ...

Primary sources
[edit]- Discussion moved from User talk:Edcolins#Primary Source concerns on Hot Swapping.
Questions about the changes you made removing my additions. I would like to correct whatever they are so we improve this page. Perhaps you can help. I have access to source material on this topic from and including some of the people who worked creating the technology.The content was factual and key to the subject. Not having it is one of the reasons Wikipedia receives much criticism. Please help. Deansmith750 (talk) 16:45, 19 November 2016 (UTC)
- Thanks for your message. We need reliable, published secondary sources especially when it comes to claims about who invented the technology. The issue with "source material on this topic from and including some of the people who worked creating the technology" is precisely that such material qualifies as primary sources. See WP:PRIMARY. Are you aware of any secondary source about who actually invented the technology? --Edcolins (talk) 16:53, 19 November 2016 (UTC)
- No question as to who invented and was issued copyrights. Lots of official proof from governmental agencies. Many historic records are easily accessible via searches and links. I have patent application, copyright history, trade mag stories, marketing materials and misc other records. If I cite the patent application (via gov office), trademark registration with history (via gov office), then the companies published materials and last industry materials showing they recognized "hotplug" was a registered trademark (naming the owner), do I need all these? Deansmith750 (talk) 22:13, 19 November 2016 (UTC)
- The "official proof[s] from governmental agencies", including patent applications, are primary sources and should not be used alone. Could you please point to specific secondary sources available online, such as books, magazines, or scientific papers? Thanks. --Edcolins (talk) 11:15, 20 November 2016 (UTC)
- I have not found extensive sources pro but none con to what I wrote. This is the reason I was forced to use these cites. They conform to known history. You likely know, using secondary only and not primary are not absolute requirements. I understand your original concern regarding use of only Primary and your assertion "governmental agencies, including patent applications, are primary sources". However, careful reading of the Wikipedia pages show "primary sources that have been reputably published may be used". And applying the fact to this case do show certain items published from these groups can be considered "Secondary". WP:SECONDARY says secondary may or may not be "independent" sources". WP:WIS defines governmental agencies as independent on these type of cases. There is a difference between filing a legal document or publishing a report and that an issuing of an order or determination. Simply in this case (Hotplug or hot swapping), the issue actually comes down the end result and looking at history. That is whether there was a copyright or patent issued (not filing records) and how the industry responded to the registration and technology created/disclosed. Facts I found: (1) The parties (primary sources) I identified claim to be inventors, published extensive materials, built and sold products containing the technology and no one has been found that has disputed this (all of this over many years). (2) No one other than who I identified claiming to have invented the technology. (3) No examples found until who I identified had products embodying use of the technology in the stated application. (4) no patent has been issued. Application was made but not completed by the parties I identified. Industry copied this technology, it has become a standard and today there are many examples of its implementation. (5) Copyright was filed and issued (registered) without objection. (6) Industry & governments accepted and referenced (crediting ownership). (7) Some in the industry avoiding using the term "Hotplug" and in some cases began calling the exact technology "hot swap" or "hot swapping". Please restore the the words and cites.

- The cites you added "(2002) Computer Architecture: A Quantitative Approach" and "1992 Present and future of distributed power systems" are fairly limited in defining this topic and are newer than the cites I used. There are much better ones. Improved page if use them along with the original and pioneers of the technology. I would like your help on this page. I does need to include the invention and evolution. Deansmith750 (talk) 03:46, 21 November 2016 (UTC)
- If I understand you correctly, you would like to add to the article that a certain person invented the technology. However, it seems that you have not been able to cite any reliable, published sources that directly support your claim. To me, this means that the information you would like to add cannot be added to the article since doing so would violate Wikipedia:No original research. --Edcolins (talk) 20:42, 23 November 2016 (UTC)

- My objective was to improve this topic with clarity and fill in missing history. The goal was reliable, factual and complete sources. This was not a quick or easy task. No, not violating Wikipedia:No original research. I used many cites, just not the ones you apparently like. And I offered to add more, but you objected to those as well. For some strange reason, you have taken a very narrow view and have chosen to ignore the fact my cites are allowed in WP:PRIMARY and WP:SECONDARY. More amazing, I am mystified by your objections. I see from your User Page, you focus of patents and related topics. Your changes and cites remind me of a lawyer who represents a client that wants an alternate view.
- To your question, ".. would like to add to the article that a certain person invented the technology. However, it seems that you have not been able to cite any reliable, published sources that directly support your claim.". This is incorrect to say "able to cite any reliable, published sources that directly support your claim". The major claim as to naming the inventor of the term "hotplug" for this technology is clearly proven by the US Patent and Trademark Office granting registration without objection and industry use and cites for competing products. The cites I used were clearly published. These can be looked up by anyone who makes a serious effort to search. As to reliable, I checked Wikipedia:RS and every one of the cites meet the requirements.
- I have thoroughly researched this topic and worked to figured out truth from fiction and accurate and incomplete publications. In this process, I have found many errors, including on Wikipedia and a host of patents that should not have been issued because they were known and not novel. For example, see Clariion history and their 1994 patent 5371743 vs my cites coming from 1991 Ad on page 35, or 1990 marketing material IAS or the 1991Hotplug Trademark the describing the precise hotplug or swappable process.
- Apparently, you and I have different views of this topic and what is useful to readers. I would accept your objections and changes, except for a major problem. The changes you made significantly ignore the history and useful content needed on this page. The cites you used are rather weak side quotes, not actual on the topic and absent useful content. However, while I do wish there were many more clear WP:SECONDARY sources, what I wrote and cites I offered are NOT contradicted anywhere and add content to this topic while your versions are absent. I have found the inventor's company was identified as one of a handful of the very first to produce disk array products (primarily where hotpug and swappable function is used) according a very strong secondary source (see page 16 of Disk Array Market from UCSD.EDU).
- Perhaps, we can agree on a revised words and cites. I asked and would appreciate your help on improving this topic and happy to share the results of my research. Deansmith750 (talk) 07:38, 27 November 2016 (UTC)
- Thanks for the explanations. I have just started a section "Trademarks". Let me know whether you are happy with the wording. You have also cited these three references:
- 1991 Ad, page 35 - Since "Articles should be based on reliable, third-party, published sources with a reputation for fact-checking and accuracy" (WP:RELIABLE), I don't think this ad can be used to support anything in the article. An ad by Core International is almost by definition not a third-party source for a claim relating to Core International.
- Bennett A. Greene, Hal Prewitt, Total Data Management, Department of Communications, CORE International, Inc., Copyright 1991 (publication date unclear [1]) - Again, marketing material from Core International cannot, in my opinion, be used to support a claim relating to Core International. We need a third-party source.
- page 16 of Disk Array Market from UCSD.EDU - Seems to be a reliable source, but it does not seem to contain any occurrence of the terms "hot swapping", "hot plug", or "hot plugging".
- If there is no reliable, third-party source on the origin of the technology, it seems better to wait for a reliable source to be published in that respect. --Edcolins (talk) 14:32, 27 November 2016 (UTC)

- We are having a problem communicating. I wrote "My objective was to improve this topic with clarity and fill in missing history". The cites are not being used to support a claim made by Core. This is about HISTORY. They were PUBLISHED and the dates are known. These events are undisputed. I showed you more than 3 cites and told you I have found many more. You continue with an extremely narrow view and once again incorrectly apply WP:PRIMARY. The first line is key "Policy: Unless restricted by another policy, primary sources that have been reputably published may be used in Wikipedia, but only with care," Best I can tell, you have zero interest in improving this topic and solely focused on blocking useful content and removing work of other contributors. Allow my work. Then, if you disagree, find and cite anything that contradicts. --- Deansmith750 (talk) 18:13, 27 November 2016 (UTC)
- If you have found "many more" sources, why aren't you disclosing them? You have added here the following: "... the late 1980s, when technology was invented by Hal Prewitt, ...". But the only reference you have provided for that is marketing material authored by Mr Prewitt himself. I have not checked whether in this document Mr Prewitt is actually claiming to have invented the technology, because in any event we need an independent, third-party source for that claim. If you still don't agree on this, you may wish to request a WP:THIRDOPINION. --Edcolins (talk) 19:46, 28 November 2016 (UTC)

- After reading this discussion, I reviewed the edit history of this article. In my opinion, the "Trademarks" section that Edcolins added to the article on November 27, 2016 is a good compromise; the trademark status of the term is not, nor should it be, the focus of this article. The extent to which Deansmith750 had previously edited the article to focus on Core International and the trademark was disproportionate to the significance of that aspect in relation to the overall article topic (in my opinion).

Sun SPARCstation cradle
[edit]Just a detail: The use of the Sun SPARCstation 4/5/20 cradle (picture) may not be correct. To my knowledge from e.g. Solaris 9, hot-plugging of a drive requires (in addition to SCA-2) the SCSI bus to be "quiescent", but this is not possible if the root filesystem uses that bus. So, with only one SCSI bus, hot-plugging is not possible. A HDD with a SPUD bracket makes more sense. --Mopskatze (talk) 00:24, 2 February 2017 (UTC)
Dismounting in USB
[edit]A notice should be made that, with USB, while USB drives can be plugged and unplugged without physical problems, it can corrupt the file system. USB mass storage has to be ejected or dismounted before unplugging it. USB Media Transfer Protocol devices however don't become corrupt if unplugging during writes. Please write up properly and include this information in the article. --Error (talk) 21:54, 5 October 2019 (UTC)
