** URGENT ** ESX:  Datastore inactive (Lost Communication) after SAN firmware upgrade

Hi All,

I've just updated the firmware on our SAN disk.  It completed successfully.  We have 10 volumes and 9 are running as expected.  1 is in an inactive state.

The SAN is an HP P2000.  The volume is 2.6TB, there are 3 virtual machines on the volume.  I'm not sure if its relevant but the disk is a VMFS3 that is showing as 2TB (0.6TB lower than the volume, so i guess there's a file size limit).

Error 1
Error 2
Error 3

All help is welcome.

What version of the firmware did you apply?
What version of the firmware was previously installed?
Do you have a single controller or dual controller?
What steps have you performed to troubleshoot the issue?
On the Tasks & Events tab are you seeing any telling events?
On the Alarms tab, what alarms are being displayed?
Are the physical drives responsible for this LUN all online and functioning?

I would get this escalated straight to HPE. If it all worked before the firmware update, and NOW....

you've lost a LUN...

Why did you apply the firmware update for what reason ? - FUN ?

also check that firmware and SAN is on the HCL.

Restart Host, Re-scan HBA, restart MSA

managed to get it sorted.  I switched off all the VM's unmounted and remounted, and they seem to be ok now.

Despite its humble beginnings, phishing has come a long way since those first crudely constructed emails. Today, phishing sites can appear and disappear in the length of a coffee break, and it takes more than a little know-how to keep your clients secure.

The SAN had a lot of disk latency.  I backed all the servers up so thought the worst that can happen would be i have to spend the weekend on the phone to HP.

After re-mount the volume i removed a couple of the server from the inventory.  When I put them back in it's asking if they have been moved or copied?

Move is the correct answer.

Make sure you understand WHY!

Copied = creates new UUID
Moved = keeps UUID

Though answer is already provided above but i worked on such case where i got all back after doing firmware upgrade on my  esxi host as well ,but its something you need to plan & take care all should be compatible to HCL
