AIX 5.3 cannot detect Clariion disk after PowerPath is removed

Question

Hi, On my AIX 5.3 server, with one lun assigned from CX600, it sees the disk initially. But, after I remove PowerPath, AIX no longer sees the disk even after reboot. Any idea?

tsx · Answer

No it doesn't show. It doesn't even pickup any new luns that are assigned to it.

dynamox · Answer

can you try changing failover mode to 0 since you do not have failover software now. Also make sure auto-traspass on the luns is disabled.

cfgmgr -v and then lsdev -Cc disk ..do not show hdisk# ?

dynamox · Answer

from Clariion perspective everything looks logged-in in 'Connectivity status' ?

I reinstalled PowerPath and it doesn't pickup any disk any more. Here's more info...
