zpool showing faulty disks as good
A couple of days ago a disk failed on a T2000:
solaris10:/# zpool status
pool: rpool
state: DEGRADED
scrub: resilver completed after 0h19m with 0 errors on Thu Nov 13 11:35:35 2014
config:
NAME STATE READ WRITE CKSUM
rpool DEGRADED 0 0 0
mirror DEGRADED 0 0 0
c0t0d0s0 REMOVED 0 0 0
c0t1d0s0 ONLINE 0 0 0
errors: No known data errors
solaris10:/#
Pretty standard. I opened an SR and, among other things, Oracle asked me to reboot the server. Sure enough the server refused to boot:
{0} ok boot
Boot device: disk0 File and args:
