CX700: Vault LUN not enabled or not valid

Hi all! I have a problem with my CX700 w. Flare 2.24: Whenever I try to enable the write cache, I get an entry in the event log saying "Vault LUN not enabled or not valid", Event code 0x7bd. The CX700 is all ok, all disks are fine, vault disks are fine as well, both SPs working, both SPS are fine and charged, no error at all showing in Navisphere. What can I do?
Thanks!

Thank you for the tips.

After a bit googling I was able to access the SP OS's via EMCremote. I've tried the registry trick on both SP and reboot them without succsess.

@KHD:-)  How should I proceed? May I need do delete the hot spare luns to prevent a takeover from them.

How long should a disk be removed to ensure the system recognize it correctly as removed/faulted.

May I start with the 5th disk because at the startup its not flickering that much than the other 4 do. Or is this normal?

Thank you

Hi again, yes you can try force rebuild of disk 0-3

Drive 0-3 is the flare disks in R1 for SPA & SPB Drive 4 is vault

Do not disable HS, an take disk 0 out wait for it to finish rebuild to HS, when finish, insert disk 0

do same procedure for all flare disks (0-4)

So disk 0 out. wait! disk 0 in

disk 1 out. wait! disk 1 in

disk 2 out. wait! disk 2 in

disk 3 out. wait! disk 3 in

Try it

Hello again

It took a while until I could arrange a downtime, but finally I've solved the issue.

Thank you for your explanations.

I've found a solution I'd tried first and it was successful.

  1. Shutdown all connected server.
  2. Check if SPA and SPB is working ok.
  3. Run EMCRemote and connect to the Windows XP embedded on SPA (EMCRemote login: clariion1992/clariion1992   Windows login: clariion/clariion! )
  4. Switch off FLARE by opening a command prompt on SPA and type hfoff
  5. Reboot SPA by START->Shutdown->Reboot
  6. Wait until SPA is up again. On SPA the FLARE now is not loaded so the amber LED is on.
  7. Run EMCRemote to connect to SPB
  8. Open regedit on SPB and set registry key HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Flaredrv/Parameters/FlareVaultDelete to 1
  9. Reboot SPB by START->Shutdown->Reboot.
  10. Now the vault disk is recovering. Wait until the flickering on the disks 0 to 4 stops and SPB is up again.
  11. Connect to SPA via EMCRemote and turn on FLARE by typing hfon in command prompt.
  12. Reboot SPA by START->Shutdown->Reboot
  13. Wait until SPA is up again. On SPA the FLARE now is loaded so the amber LED is off.
  14. Startup connected server again.

Write cache is enabled, perfect.

Yes, the procedure is listed in EMC KB24378 (Enabling write cache on CLARiiON array with CRU signature or vault load errors, https://support.emc.com/kb/24378), but usually it is for Field Support personnel. For end-users please still call EMC support first.

Hi gaggaman, I'd really like to know how you solved this issue? I'm having the same problem on a CX4-120.

Regards, George.
