the days of relying on /dev/sd? are long past.
'scsi' devices renumber themselves on every boot. case in point,
server I'm configuring now... has a LSI mptsas card with 2 disks
mirrored for the OS and a megasas2 card with a large raid. when it
first came, the megaraid had 2 raids on it, /dev/sda and /dev/sdb and
the OS on the mpt card was on /dev/sdc .... I deleted these two raids
and rebooted. now the OS was on /dev/sda ... I then defined a new
larger raid60 on the megaraid, this was /dev/sdb then I rebooted and
the megaraid was /dev/sda and the boot drive was /dev/sdb
I chose to mount my raid volume with uuid
|parted /dev/sda ||"mklabel gpt"|
|parted -a optimal /dev/sda ||"mkpart primary 128k -1s"|
|mkfs.xfs -f /dev/sda1|
|uuid=$(xfs_admin -u /dev/sda1 | awk ||'{print $3}'||) # get the UUID|
|echo ||"uuid=$uuid /data xfs defaults 1 2"| |>
/etc/fstab|
|mkdir /data|
|mount /data|
as I had no need for LVM on this configuration, but
I have to say, I like Solaris's traditional disk numbering,
/dev/dsk/c0t0d0s0 is channel 0, target 0, device 0, lun 0. the channel
numbering is generally constant in a given system if you don't juggle IO
cards around.
