metattach {metadevice} {size} growfs -M {mountpoint} /dev/md/rdsk/{metadevice}

• Look at output for signs of failed disk slice

metastat -c

• Delete metadbs knowledge of dead drive so that we can format the new disk

metadb -i metadb -d /dev/dsk/c3t1d0s7

• Force a detach of all failed submirrors

metadetach -f d0 d20 metadetach -f d1 d10

• Remove knowledge of all failed submirrors from the database

metaclear d20 metaclear d10

• Unconfigure the failed disk, use output from first command for second command

cfgadm -al Ap_Id Type Receptacle Occupant Condition c3::dsk/c3t1d0 disk connected configured unknown cfgadm -c unconfigure c3::dsk/c3t1d0

• Replace failed disk

• Configure new disk

cfgadm -c configure c3::dsk/c3t1d0 cfgadm -al Ap_Id Type Receptacle Occupant Condition c3::dsk/c3t1d0 disk connected configured unknown

• Apply the working disk's format to the new disk and check that it worked.

prtvtoc /dev/rdsk/c3t0d0s0 | fmthard -s - /dev/rdsk/c3t1d0s0 fmthard: New volume table of contents now in place. prtvtoc /dev/rdsk/c3t1d0s0

• Add 2 copies of the metadevice database to the new disk for backup purposes

metadb -c 2 -a /dev/dsk/c3t1d0s7

• Re-create all submirrors

metainit d20 1 1 c3t1d0s0 metainit d10 1 1 c3t1d0s1

• Re-attach all submirrors to mirrors, will automatically begin resyncing

metattach d0 d20 metattach d1 d10

• Check to see percent of resync complete

metastat -c

• Add Disk to Existing Concat/Stripe RAID 0 Volume:

root@global.zone #> metattach {metadevice} /dev/dsk/{device_name}

• Or, if using soft partitions and there is space available:

root@global.zone #> metattach {metadevice} <extra_space>

• Find out how zone filesystem is mounted:

root@global.zone #> growfs /dev/md/rdsk/{metadevice} /dev/md/dsk/{metadevice} is mounted on /zones/global.zone/root/{mountpoint}; can't growfs

• Grow existing non-global zone mounted filesystem from global zone:

root@global.zone #> growfs -M /zones/global.zone/root/{mountpoint} /dev/md/rdsk/<{metadevice}
