Hi everyone,
I am trying to trace an LDOM's vdisks back to the SAN LUN ID's and I am getting
stuck at the MPxIO layer on the primary.
I can trace the vdisk added to the LDOM back to a vds device, which is an MPxIO
path. This vdisk was added to the LDOM guest with the "exclude" option set.
On non-LDOM hosts I can run "luxadm display" to identify the LUN by its "Device
Address", e.g.
/dev/rdsk/c6t6005076801810562300000000000052Ed0s2
/devices/scsi_vhci/s...@g6005076801810562300000000000052e:c,raw
Controller /devices/p...@400/p...@0/p...@c/SUNW,q...@0/f...@0,0
Device Address 500507680140ac83,15
Host controller port WWN 2100001b328174f2
Class secondary
State ONLINE
Controller /devices/p...@400/p...@0/p...@c/SUNW,q...@0/f...@0,0
Device Address 500507680140ac46,15
Host controller port WWN 2100001b328174f2
Class primary
State ONLINE
Controller /devices/p...@400/p...@0/p...@c/SUNW,q...@0,1/f...@0,0
Device Address 500507680120ac83,15
Host controller port WWN 2101001b32a174f2
Class secondary
State ONLINE
Controller /devices/p...@400/p...@0/p...@c/SUNW,q...@0,1/f...@0,0
Device Address 500507680120ac46,15
Host controller port WWN 2101001b32a174f2
Class primary
State ONLINE
So here the MPxIO device maps to the LUN with decimal ID 15. However, on the
LDOM's host I get a SCSI error from "luxadm display", presumably due to the
exclude option on the vdisk.
Error: SCSI failure. - /dev/rdsk/c6t6005076801810562300000000000056Ad0s2.
Is there any way around this, or another way to get the LUN ID?
We are running LDOM version 1.1 on Solaris 10 10/08 (U6). The server is a T5240
with Sun branded Qlogic cards. The SAN is an IBM SVC virtual array.
Thanks,
Spencer.
