Hi,

I am getting the error like "Some XP array disks have single path only". OS is 11.31

See the below o/p of commands.

====================

I have checked for few disk like:

#-> scsimgr lun_map -D /dev/rdisk/disk7

        LUN PATH INFORMATION FOR LUN : /dev/rdisk/disk7

Total number of LUN paths     = 1
World Wide Identifier(WWID)    = 0x60060e8015268c000001268c00000001

LUN path : lunpath7
Class                         = lunpath
Instance                      = 7
Hardware path                 = 0/4/0/0/0/0.0x50060e8015268c44.0x4000000000000000
SCSI transport protocol       = fibre_channel
State                         = ACTIVE
Last Open or Close state      = ACTIVE

My query is that why the disks showing single lunpath hardware address?

Appreciate the response.
