Hi, We have an x4500 server running OpenSolaris snv_127. We suffered a disk failure (c7t0d0) - or rather, a disk started throwing up a large number of checksum errors, so I resilvered onto a spare drive, which succeeded:
# zpool history data <snip> 2010-04-20.14:45:08 zpool offline data c7t0d0 2010-04-20.14:58:19 zpool replace -f data c7t0d0 c7t1d0 # zpool status data pool: data state: ONLINE scrub: resilver completed after 43h58m with 0 errors on Thu Apr 22 10:56:50 2010 config: NAME STATE READ WRITE CKSUM data ONLINE 0 0 0 raidz2-0 ONLINE 0 0 0 c11t1d0 ONLINE 0 0 0 c10t1d0 ONLINE 0 0 0 c13t1d0 ONLINE 0 0 0 c12t0d0 ONLINE 0 0 0 c8t1d0 ONLINE 0 0 0 c12t1d0 ONLINE 0 0 0 c10t0d0 ONLINE 0 0 0 c10t7d0 ONLINE 0 0 0 c12t2d0 ONLINE 0 0 0 c8t0d0 ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 381G resilvered As you can see, the drive c7t0d0 has been successfully replaced and no longer appears in any zpool: # zpool status | grep c7t0d0 # # iostat -En | grep c7t0d0 c7t0d0 Soft Errors: 2 Hard Errors: 4 Transport Errors: 0 # cfgadm -l | grep c7t0d0 sata1/0::dsk/c7t0d0 disk connected configured ok However when I attempt to unconfigure the sata port in preperation for replacing the drive, it doesn't work: # cfgadm -c unconfigure sata1/0 Unconfigure the device at: /devices/p...@0,0/pci1022,7...@1/pci11ab,1...@1:0 This operation will suspend activity on the SATA device Continue (yes/no)? yes cfgadm: Hardware specific failure: Failed to unconfig device at ap_id: /devices/p...@0,0/pci1022,7...@1/pci11ab,1...@1:0 I'm not sure if this is unrelated, but during the last disk failure we pulled the disk out without unconfiguring the port first, which left to an unusable unconfigured port: # cfgadm -l | grep unusable sata6/0 disk connected unconfigured unusable So I'm guessing this means we'll have to shut this server down to replace the disks. Not ideal! I'm fairly certain this used to work fine. Could this be a bug? Is it worth filing a report? Anyone have any comments?
