lspath can see only one path ...

[oliverbeat]

Hi,
AIX on SAN HP disks, lspath command return me this:
Enabled hdisk0 scsi0
Enabled hdisk1 scsi0
Enabled hdisk2 fscsi1
Enabled hdisk3 fscsi1
Enabled hdisk4 fscsi1
Enabled hdisk5 fscsi1
Enabled hdisk2 fscsi1
Enabled hdisk3 fscsi1
Enabled hdisk4 fscsi1
Enabled hdisk5 fscsi1
Enabled hdisk6 scsi0

I can't see the fscsi0 path, there is no error on the fibers it is switch etc... Any idea ?
# /opt/hphsv/bin/lshba -h
FCS FSCSI MODEL FW WWN LOC PHYSICAL LINK CMDS ATTACH DYNTRK RECOVERY NPORT ID VENDOR DOM PORT
fcs0 fscsi0 LP10000 T1D1.90X13 10000000C94B268A 04-08 U787A.001.DPM1HYL-P1-C1-T1 al 200 switch dyntrk=no delayed_fail 0x40900 Brocade 64 144
fcs1 fscsi1 LP10000 T1D1.90X13 10000000C94B267A 07-08 U787A.001.DPM1HYL-P1-C4-T1 al 200 switch dyntrk=no delayed_fail 0x20500 Brocade 32 80

# lsattr -El fscsi0
attach switch How this adapter is CONNECTED False
dyntrk no Dynamic Tracking of FC Devices True
fc_err_recov delayed_fail FC Fabric Event Error RECOVERY Policy True
scsi_id 0x40900 Adapter SCSI ID False
sw_fc_class 3 FC Class for Fabric True

Thanks in advance

Guess1: Check your switch zoning.
Guess2: Is the HD configured to present the disks to the fcs0 wwn.

To add to DukeSSD list above:

Maybe the preferred path was changed on the SAN LUN mappings. Check that as well!

I can see that hdisk2 to 5 are present twice! which means that they appear from two different paths! so maybe fscsi0 is not being used as the preferred path on the other switch any more!

Hi,

IT was a problem with the SAN, the configuration (zoning maybe ) was incorrect !

Cheers
