Iscsi on Solaris 11

15/2/2012

Install the iscsi services
- pkg install group/feature/storage-server
- svcadm enable stmf

Backup current configuration
- svccfg export -a stmf >/var/tmp/COMSTAR
If needed restore configuration
- svccfg import /var/tmp/COMSTAR

Create a new lun
- zfs create -V 2g rpool/vol1
- stmfadm create-lu /dev/zvol/rdsk/rpool/vol1
- stmfadm list-lu ; to get name of new lun id

Create a host group who are allowed to connect to the new lun (opional)
- stmfadm create-hg tx-nfs
Add members:
- stmfadm add-hg-member -g tx-nfs iqn.1986-03.com.sun:node1
- stmfadm add-hg-member -g tx-nfs iqn.1986-03.com.sun:node2

Create a view for the new lun, including access for the new host group
- stmfadm add-view -n 10 -h tx-nfs 600144F0D2D88F0000004F3BF9E30001
* -n 10 ; defines the lun number (optional)
* -h tx-nfs ; defines the host group to allow access (optional)
* -t ??? ; defines an optional target group
Enable iscsi target
- svcadm enable -r svc:/network/iscsi/target:default
Create iscsi targete
- itadm create-target -n iqn.1986-03.com.sun:iscsi01 -l iscsi01
* -n ; an optional name for the iqn
* -l ; optional alias for the iqn

Test the new target using automatic discovery from the same or other server:
* Define a readable iqn name, and alias for the current server
- iscsiadm modify initiator-node -A iscsi01 -N iqn.1986-03.com.sun:node1
* Enable static discovery
- iscsiadm modify discovery -s enable
* Add a static configuration for the new lun
- iscsiadm add static-config iqn.1986-03.com.sun:iscsi01,10.0.1.51
* Look for new luns using devfsadm
- devfsadm -i iscsi

Verify the new lun:
- echo | format ; look for a lun named SUN-COMSTAR
- iscsiadm list target -S

Make a zfs pool on the new disk
* If the system is running on AMD/Intel (x86), fdisk the disk with a solaris partition
- echo | format
- identifiy the new disk; look for SUN-COMSTAR
- fdisk -B c0t600144F0EA3E8C0000004F3BBA1C0001d0p0 # Add p0 to the end of the name
* Create the zpool
- zpool create newpool c0t600144F0EA3E8C0000004F3BBA1C0001d0

One interesting thing is if you get to building a larger storage server is to get a schema in place for initiator naming, Group naming, and target nameing. That helps a lot. Granted, the FISHworks ZFS Appliance BUI makes it tremendously easy. The only gripe I have is that, when taking snapshots, your can run your your pools out of space quite easily because there is not ready way to track "real" disk usage. Only the thinly provisioned LUN space shows, not the LUN plus snapshot consumption.
