HPE MSA firmware can be tricky to update. Below are a series of notes to help with the process.
*In any case, make sure backups are good before starting the party*
- If you ssh or telnet into the MSA, you can run show configuration and it will dump the firmware and drive models.
- This process also gives you serial numbers, IP addresses, volume names and sizes, etc.
- You should do this before and after the upgrade.
- If you need to call for support on an MSA, they will need the CHASSIS_MIDPLANE Serial Number for reference.
- You are supposed to be able to flash the MSA bundle online; this updates everything but the drives. The controllers should fail back and forth on their own.
- Sometimes HPE will suggest turning off the partner update and have you manually flash one controller at a time.
- If you are going to flash them online, I would suggest trying to do it when I/O is lower.
- This process can take a while, so plan 2-4 hours to flash these controllers.
- The newer models, x04x and up, have been much better at this process. Older ones sometimes had issues flipping over and controller firmware upgrades has killed controllers at times.
- I would recommend opening a ticket with HPE for the SAN and have them bless the system and the planned steps before the upgrade. This also provides you with a starting point and reference in case you need to call back for any issues.
- Be aware that the MSA firmware release numbers are not necessarily logically sequenced, i.e. VL270P003-01 is newer than VL270R001-01, so you need to confirm the current bundle versions. You can do that here: https://h41111.www4.hpe.com/storage/msafirmware.html
- There is separate firmware based on drive model; note that there are a few hundred models. I have seen MSAs with several models with the same part number in a single shelf due to replacements or expansions over time. Here is a good reference: https://www.hpe.com/storage/MSADriveFirmware
- Per HPE “Disk drive upgrades … is an offline process. All host and array I/O must be stopped prior to the upgrade.” I usually shut down the VMs or anything else active on the SAN. Sometimes I leave the hosts online to watch the alerts on them, sometimes I just shut them all down.
- Drive updates usually go fairly quickly; you should figure 1-2 hours per shelf.
- I usually check the drive firmware and if any need to be flashed I plan to do the whole upgrade offline during a dedicated maintenance window.
