I have a very strange issue with creating LUNS on this AIX server!
Output below:-
powermt display dev=all
Pseudo name=hdiskpower1
CLARiiON ID=CK200043600821 [LONIBM2]
Logical device ID=600601605A101200A882025D6C63DB11 [LUN 10]
state=alive; policy=BasicFailover; priority=0; queued-IOs=0
Owner: default=SP B, current=SP B
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
0 fscsi0 hdisk5 SP B1 active alive 0 0
Pseudo name=hdiskpower0
CLARiiON ID=CK200043600821 [LONIBM2]
Logical device ID=600601605A101200CA2376BC9A62DB11 [LUN 5]
state=alive; policy=BasicFailover; priority=0; queued-IOs=0
Owner: default=SP B, current=SP B
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
0 fscsi0 hdisk2 SP A1 active alive 0 0
0 fscsi0 hdisk3 SP B1 active alive 0 0
The first LUN is hdiskpower0 which you can see is fine, but when I create the second LUN (hdiskpower1) I only get the one path!!!!
I have tried this about 5 times and always get the same output, any ideas?
As soon as I have created the LUN it always fails over. The hdiskpower1 LUN should be on SPA but as soon as it gets allocated on the AIX server it fails over to SP B!
