Who confirmed my thought that the 'good' slice on the failed disk had to
be hotswapped out before the disk was replaced.
Thanks for the replies.

All,
I have checked the archives and could not find the exact syntax that
I am looking for. Hope someone can help.
E5000 running Solaris 2.5.1 using DiskSuite 4.0
Checks of log files show that a slice in a RAID5 set has errored, and
was replaced by a hot spare. This will be replaced when the engineer
arrives. I am just double checking the commands to resynch the disks
BACK after the physical replacement.
# metastat d15
d15: RAID
State: Okay
Hot spare pool: hsp002
Interlace: 16 blocks
Size: 4142000 blocks
Original device:
Size: 4143168 blocks
Device Start Block Dbase State Hot Spare
c1t1d1s7 170 No Okay
c1t3d1s7 170 No Okay
c1t5d1s7 170 No Okay c1t1d3s7
c1t5d1 is a 2.1Gb disk, split into 2 slices. Only 1 slice has errored
and switched to a hot spare.
If I replace the disk with the bad slice, what happens to the 'good'
slice on it - will that automatically switch to a hot spare as well?
And then, after the physical replacement of the disk, would I use these
commands:
metareplace -e d15 c1t5d1s7
metareplace -e d20 c1t5d1s6
I am not sure of the above syntax - for the 'component', do I specify
the failed slice as I have done? (according to the man page this slice
will be resynched and the hot spare slice will be returned neatly to the
hot spare pool - is this correct?)
Thanks and I will summarise.
