** 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.

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

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

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?

so you need to read my EE Article then to Answer that question

HOW TO: Select the right answer to "I Moved It" or "I Copied It" in VMware vSphere (ESXi)
detox1978Author Commented:
Thanks for the link.  So i should pick I moved it, as there isnt another on the network.
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Move is the correct answer.

Make sure you understand WHY!
detox1978Author Commented:
Copied = creates new UUID
Moved = keeps UUID

no problems
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
