Multiple errors in AIX 5.3
Hi Admins,

Code:
# lspath -H -l hdisk2
status  name   parent
Enabled hdisk2 fscsi0
Enabled hdisk2 fscsi0
Missing hdisk2 fscsi2
Missing hdisk2 fscsi2
Enabled hdisk2 fscsi0
Enabled hdisk2 fscsi0
Enabled hdisk2 fscsi2
Missing hdisk2 fscsi2

Multi path IO status is shown as Missing for hdisk2. I want to enable the same.

Please tell me whether i can enable the same online.Any other implications are ther with this. Because server is very critical one.

Regards
newaix

first check for errors in error log
Code:
errp |more 
errpt -aj errorcode

Second Diagnostic
Code:
diag

If still nothing interesting
Remove second fsc
Code:
rmdev -Rdl

Rediscover it with Config Manager
Code:
cfgmgr

If you still do not have paths contact SAN team
it is SAN/hardware/Cable problem

Hi
Execute the below command on the vio client lpar:
Code:
# lspath -HF "name path_status connection parent status" -l hdisk*

This will show the lun id's of the storage luns. If the lun id's are different in a dual vio situation then please check on the vio lun mapping.
