Hi,
I just moved a machine (AS 800) running 5.1A PK4 with 2 attached storage
devices. Upon powering up and rebooting one of the disks isn't showing up.
When I issue:
hwmgr -show scsi -full
it shows (just a relevant snippet, not the whole output because there are
more attached devices than just these):
SCSI DEVICE DEVICE DRIVER NUM DEVICE FIRST
HWID: DEVICEID HOSTNAME TYPE SUBTYPE OWNER PATH FILE VALID PATH
-------------------------------------------------------------------------
47: 8 sif disk none 2 1 dsk6 [2/0/0]
WWID:03100030:"RZ2ED-LS (C) DECSEAGATE ST11820LC LK767218"
BUS TARGET LUN PATH STATE
---------------------------------
2 0 0 valid
SCSI DEVICE DEVICE DRIVER NUM DEVICE FIRST
HWID: DEVICEID HOSTNAME TYPE SUBTYPE OWNER PATH FILE VALID PATH
-------------------------------------------------------------------------
48: 9 sif disk none 0 1 (null)
WWID:03100030:"RZ2ED-LS (C) DECSEAGATE ST11820LC LK768717"
BUS TARGET LUN PATH STATE
---------------------------------
2 1 0 stale
SCSI DEVICE DEVICE DRIVER NUM DEVICE FIRST
HWID: DEVICEID HOSTNAME TYPE SUBTYPE OWNER PATH FILE VALID PATH
-------------------------------------------------------------------------
49: 10 sif disk none 2 1 dsk8 [2/3/0]
WWID:0c000008:0000-0e11-001e-5872
BUS TARGET LUN PATH STATE
---------------------------------
2 3 0 valid
You can see that dsk6 and dsk8 are fine but what should be dsk7 shows
(null). The PATH STATE for dsk6 and dsk8 is 'valid' but the PATH STATE for
what should be dsk7 is 'stale'.
When I issue 'disklabel -r dsk7' I get:
disklabel: dsk7: No such device or address
I don't see any errors in either /var/adm/messages or from the output of
'uerf -R|more'. Also, the yellow fault light is NOT on.
Any thoughts?
Thanks!
Andy
