Updating Disk Firmware - is it recommended and how long does it take?

Ralf Seefeldt — Mon, 16 Feb 2015 08:52:43 GMT

Hi everybody,

I have to patch a system environment including two MSA2312fs with 4 enclosures and 40 Disks each.

The MSAs has to receive a new firmware to stay compatible with the blade enclosure.

The disks of the same type have nearly all the same firmware. So, I only must update one disks firmware.

At this point of planing, I have two questions:

- Is it recommended to update the firmware of the disks to the latest version? There are no problems with the storage so far.

- How much time have I to calculate for updating one disks firmware? As all disks are part of a vdisk, I would have to update the firmware one disk at a time.

Any hints, that help me with planning are greatly welcome.

Bye

Ralf

Hello Ralf,

"The disks of the same type have nearly all the same firmware. So, I only must update one disks firmware."

Does this mean only one disk needs updating ?

if all disks needs an update then a downtime needs to be planned depending on the number of disks to be upgraded.

NOTE: Disk drive upgrades on the HP StorageWorks MSA2000 is an offline process. All host and array I/O must be stopped prior to the upgrade. For more information, see the HP StorageWorks 2000 Family Modular Storage Array reference guide

Hi Rajiv,

thank you for your reply.

Yes, only one disk has a older FW than the other disks of the same type. This FW-update is a must.
Another 34 Disks hav a FW, where a newer FW is available. I'm not sure whether or not to uptadt those disks.
i currently are planing a Downtime for Patching two blade enclosures and two MSAs. Thus I have downtime - and I have read all the best practice that corellate to my environment.

What I don't have is a rough estimate, how much more downtime I have to ask for, if I want to update the firmware or 35 disks.

Bye

Ideally I'd estimate about 5 mins per disk though it may take 5 mins or lesser. To be on a safer side I'd say 35 X 5 = 175mins i.e approximately 180 mins (3 hours).

Since you have downtime available better to update all the disks in one go.

Thanks & Regards,

Rajiv
