can you paste them anyway ?
Note: If you have more than one adapter, I believe you can specify -aALL in
the commands below, instead of -a0
I have 2 disks (slots 4 5) that are removable and rotate offsite for
backups.
To remove disks safely:
zpool export removable-pool
export EnclosureID=`MegaCli -PDList -a0 | grep 'Enclosure Device ID' |
uniq | sed 's/.* //'`
for DriveNum in 4 5 ; do MegaCli -PDOffline
PhysDrv[${EnclosureID}:${DriveNum}] -a0 ; done
Disks blink alternate orange green. Safe to remove.
To insert disks safely:
Insert disks.
MegaCli -CfgForeign -Clear -a0
MegaCli -CfgEachDskRaid0 -a0
devfsadm -Cv
zpool import -a
To clear foreign config off drives:
MegaCli -CfgForeign -Clear -a0
To create a one-disk raid0 for each disk that's not currently part of
another group:
MegaCli -CfgEachDskRaid0 -a0
To configure all drives WriteThrough
MegaCli -LDSetProp WT Lall -aALL
To configure all drives WriteBack
MegaCli -LDSetProp WB Lall -aALL
