FC60 LUN Disappearance on Controller
FC60 Disk Array is connected with RP8400 Server. Fan and Power Unit were changed and then RP8400 Server was rebooting, this created unique problem -> LUN Capacity did not show right on one controller. Once the controller was reset, LUN capacity came back. Some people say, it was because of firmware in FC60 (current one is HP10). It should be HP12. If we do not upgrade, this problem can happen again on any hardware replacement on server. I want to confirm that firware is the only reason for this kind of problem or any other reason. Your suggestion will be appreciated.

Re: FC60 LUN Disappearance on Controller
You should upgrade to at least HP11.
BTW, where fan and power unit were replaced - in FC60 or RP8400?
What was exact problem - 'LUN Capacity did not show right on one controller'? Did you use 'diskinfo -v' and compared between different FC60 controller device paths? Was host unable to access data of the LUNs?
Does host have AM60Srvr software installed and running? Did you watch FC60 logs (amlog)?
You know even very very fault tolerant system will crash if you'll not notice one-by-one component failures.
I do not believe this issue you had is because of fan and PSU replacement. It happened before, but host noticed it only after reboot/rescan.
So the conclusion for you is to upgrade to HP12, install AM60 Server and montitor 'amdsp -a' (general FC60 state) and 'amlog' (FC60 logs)

Re: FC60 LUN Disappearance on Controller
In addition, We are worried about having other more serious problems if we continue to use the old firmware HP10 and HP11 that are used on our two FC60's respectively. If you know something about the risk of the old firmware, please help us with informaion.

Re: FC60 LUN Disappearance on Controller
please see my previous post. Amdsp output is really incorrect, although hardware components states are GOOD/OPTIMAL.
But I would not give any recommendations and develop actions plan here because I'm lack of information (serial debug logs).
I strongly recommend to do the following: a) make FC60 full data backup and b) call HP to fix FC60 and upgrade firmware.
Maybe simple FC60 power cycling (with correct order: OFF: stop host activities [unmount/deactivate], wait until FC60 yellow cache led will go off, power off MAIN controller enclosure and only then disks; ON: power up disks, wait for 30 seconds, then power up main controller enclosure) will solve the issue, but I would not take responsibility for it. That's why I'm asking you to call HP - to have everything analyzed and action plan with contingency developed.
Good luck!
