In this documentation you will be shown how to add and attach volumes
to a Solaris environment from the EqualLogic SAN.
For consistency we will be using the following Disk for our Testing and
Documentation.

Once you get the filesystem laid out label to disk to save your changes
partition> label
You will need to do this for every disk that you added in the SAN iSCLI
Utility.
--------------------------------------------------------------------------------------------------------
SETTING UP THE ISCSI VOLUMES
Once the disk have been formatted you will need to setup the
metadevices
# metainit -a -f -c 2 c3t0d0s4 c3t4d0s4
# metadb
flags first blk block count
a u 16 1034
/dev/dsk/c3t4d0s4
a u 1050 1034
/dev/dsk/c3t4d0s4
a u 16 1034
/dev/dsk/c3t0d0s4
a u 1050 1034
/dev/dsk/c3t0d0s4
Next you need to create the logical volume by executing the following
command
# metainit -f d8 2 1 c3t0d0s0 1 c3t2d0s0
d0: Concat/Stripe is setup
# metastat
d8: Concat/Stripe
Size: 83522880 blocks
Stripe 0:
Device Start Block Dbase
c3t4d0s0 0 No
Stripe 1:
Device Start Block Dbase
c3t0d0s0 1008 No
Once the Concatenation is setup you will need to modify the /etc/vfstab
file
# vi /etc/vfstab
/dev/dsk/c3t4d0s0 /dev/rdsk/c3t4d0s0 /u01 ufs - yes
-
TO
/dev/md/dsk/d8 /dev/md/rdsk/d8 /u01 ufs - yes -
# df -k /u01
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c3t4d0s0 41098241 9 40892416 1% /u01
# umount /u01
# mount /u01
# df -k /u01
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d8 30839956 9 30634131 1% /u01
Now you can grow the filesystem to include both of the volumes you
previously setup
# growfs -M /u01 /dev/md/rdsk/d8
# df -k /u01
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d8 30839956 9 30634131 1% /u01
--------------------------------------------------------------------------------------------------------
INCREASING AN EXISTING CONCATENATED VOLUME
Make sure the disk is able to be seen by the system using the ISCLI
Utility and then FORMAT the disk.
# metattach d8 c3t5d0s0
d8: component is attached
# growfs -M /u01 /dev/md/rdsk/d8
# df -k /u01
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d8 41098241 9 40892416 1% /u01
