A Sun Ultra-45, connected via SCSI-LVD to a JetStor 416S JBOD
that talks SCSI to the host and holds (12) SATA 1TB drives.
The JBOD enclosure was used to build (1) raidz1 pool, using all (12)
about six months ago.
# zpool upgrade -v
This system is currently running ZFS version 4
# cat /etc/release

Yesterday I started a zpool scrub on the pool.
About 20 minutes into it I pushed a drive enclosure release button,
ejecting a drive (c2t1d0).
I didn't realize the drive was a member of the raidz1 pool.
10 seconds later I re-inserted the drive.
ZFS started resilvering the pool, pushing the one spare drive into
This resilvering is taking some time; it is expected to finish late
# format -e
I could see the drive c2t1d0, but the string representing the disk,
was instead showing a string indicating 0GB.
The physical path for c2t1d0 is
I was seeing a lot of kern.warning in /var/adm/messages,
WARNING: /pci@1e,600000/pci@0/pci@3/pci@0/scsi@8/sd@1,0 (sd6)
Corrupt label; wrong magic number
The load on the system was up around 12, and was sluggish to respond
zpool status -x
and saw (roughly)
c2t1d0 UNAVAIL (sd6)
c2t2d5 INUSE (sd24)
After about a half-hour, and failing to get the /var/adm/messages
decrease in frequency, I issued:
# cfgadm -c unconfigure c2::dsk/c2t1d0
That succeeded, the drive was reported offline in /var/adm/messages,
and the kern.warning
I then tried:
# cfgadm -c configure c2::dsk/c2t1d0
and I get
cfgadm: Hardware specific failure: failed to configure SCSI device: I/
Using cfgadm with a -f option does not change the output.
When I issue:
# cfgadm -l c2::dsk/c2t1d0
Ap_Id Type Receptacle Occupant Condition
c2::dsk/c2t1d0 disk Connected unconfigured unknown
# zpool status
status: One or mor devices could not be opened. Sufficient replicas
for the pool to continue functioning in a degraded state.
Action: Attach the missing device and online it using 'zpool
scrub: resilver in progress, 76.75% done, 5h27m to go

Could I get some help on how to get the disk connected again?
At this time I don't think the disk could be burned out just because
I ejected it then inserted it back into the JBOD enclosure 10 seconds
