Dell PS Series Equallogic firmware v9.1.5 and v8.1.14 have been released

Hello,

 The latest firmware is now available at https://eqlsupport.dell.com

Issues Corrected in Version 9.1.5

This version of PS Series firmware includes all bug fixes that were incorporated into earlier
releases.

Hardware

•  A PS6610 array panicked during a controller failover due to an internal transitory state of the
spare drive when spun up.

• After a CMC reset, if the firmware detected that the CPU temperature on a PSM4110 reached or
exceeded 95C, the array shut down after 50 seconds. The timer was increased from 50 seconds to 3.75
minutes. This increase allows the PSM4110 to communicate its fan request information to the M1000e
and expect the thermal response effect.

 

Networking

•  Initiators might erroneously fail to log into a single volume with Local reset initiated due to
network errors.

Protocols
Support for SSLv2 from PS arrays has been disabled.
• Garbage collector tracker flags were corrected to fix an issue with page consumption post SCSI
unmap processing, which may have accumulated over time inducing performance penalty.

 

Replication

• Cross-platform replication snapshots were deleted even if the volume had an on-going replication
scheduled or online activated DR snapshots.

• A cross-platform replication process hung because persistent connections were being logged out
and logged in numerous times.

Don

Re: Dell PS Series Equallogic firmware v9.1.5 and v8.1.14 have been released

Hello, I notice that 9.1.5 has been pulled from the support site as of this morning.  I would like to know if this is an error or if there is a problem with this version.  I have already installed 9.1.5 on one of my groups and was planning to update two other groups soon.  Please advise. 

Re: Dell PS Series Equallogic firmware v9.1.5 and v8.1.14 have been released

Hello,

 An issue was recently identified in Dell EMC PS Series firmware versions 9.1.5 and 8.1.14 which could, in rare circumstances, negatively impact array operations. If you have previously downloaded either of these firmware versions and have not yet installed it, Dell EMC recommends that you not install it at this time. An updated version of the firmware will be made available shortly to replace the affected versions. If you have installed either of these firmware versions, please contact your Dell EMC technical support representative. 

Regards,

Don

Since you don't yet have a fix, can you be a little less coy about what the issue is, who may be affected by it, and what mitigations there are currently?

I called in.  The support engineers were not given details of exactly what the problem is yet or how it gets triggered.

If you are on 8.1.14 the easy option is upgrade to 9.0.9

If you are on 9.1.5 they can give you the secret commands to allow downgrading without reset I guess.  (You have good backups already right)  

 

Or you can live with the unknown peril until a patch arrives.

Seeing as the upgrade to 9.1.5 was the only thing that fixed a different issue we were having where we were seeing latency around 15 *seconds* (15000 ms) I am keen to hear a tiny bit more about why I need to roll back.

Re: Dell PS Series Equallogic firmware v9.1.5 and v8.1.14 have been released

Hello,

 Those that have seen the issue it causes the array to be totally unavailable, not slow.  So the issue you are now seeing is not likely related to the removal of the firmware from the website.

 Please open a support case on the performance issue.

Regards,

Don

Re: Dell PS Series Equallogic firmware v9.1.5 and v8.1.14 have been released

We need some more information here.  Given the nature of these devices many of us can not just get an outage window to roll back firmware without knowing exactly what is at risk and under what circumstances.

I called into support and spoke to an engineer who tried to get more information for me and all he could come back with is the same message we received in the email, that in some rare circumstances the array could be negatively impacted.

I don't think it is too much to ask that we be told, directly, what the circumstances are, and exactly how impacted we will be.

Dell is putting a lot of stress on a lot of system admins by withholding this information.  I get to sweat it out for at least the next several days until I can get a window scheduled to roll this firmware back.  For all I know both of my SANs that I just upgraded to 9.1.5 this past Saturday are about to fall out from underneath me and I don't even know if that just means a momentary hiccup in connectivity or total loss of all data.

Re: Dell PS Series Equallogic firmware v9.1.5 and v8.1.14 have been released

Hello,

 You can downgrade from 9.1.5 to 9.1.4 without doing a reset.  Same goes for 8.1.x.  You use the same process as upgrading using the CLI.  Transfer the 9.1.4 kit to the array and at the CLI type 'update'.   The prompts will guide you through the process.   Then restart array to complete the downgrade.

Trying to downgrade a major rev, like 9.1.x to 8.1.x would require a reset of the array.

Don

Hello,

 For the moment that is the messaging we have. No one thus far affected has lost any data.  The array goes offline, making the data unavailable until the issue is resolved.  Then the firmware downgraded to prevent the issue from reoccurring. 

Regards,

Don
