Hello there. I could`nt find CLARiiON forum so I posted my question here.

There is an old CLARiiON CX4-120 with invalid power supplies (so w cache is disabled) and AC fault is happened recently. Now 2 of LUNs are offline and there is no option to bring them online in context menu. Any suggestions?

flare 04.30.000.6.509

base 04.30.000.6.538

unisphere 1.0.52.1.0073

update: I`ve tried naviseccli:

C:\Program Files (x86)\EMC\Navisphere CLI>NaviSECCli.exe -h 194.135.107.92 -user admin -password "Xxxxxxxxx" -scope 0 luncache 1 -list Error: luncache command failed This version of Core Software does not support luncache -clear or l uncache -list on Pool LUNs

This LUN is indeed a part of storage pool and there is a message in the pool properties:

An error occurred while accessing the Storage Pool.  Please resolve any hardware problems and retry the operation. (0x712D8514)

However there are no errors on the dashboard.

update2: I`ve tried naviseccli 7.32.25.1.63 with no luck. Storage pool stuck with message 0x712d8514 and there are a lot of reccommendations to open case in Tech Support, but the support for this storage system is not available for me. Any ideas?
