Sometimes the administrator needs to make available all physical disks from a storage to another storage.
Share physical disks using iSCSI
- Storage A (192.168.150.1): This is the “master” that sees disks over iSCSI from the other storage
- Storage B (192.168.150.2): This is the “slave” that only provides access via iSCSI to the “master” storage
The procedure is currently available only from “unsupported shell”, but will be made available in the web configuration interface with a future software update.
- Configure iSCSI initiator on Storage A (Master)
root@StorageA:~# iscsiadm list initiator-node | grep 'Initiator node name: ' | awk '{print $4}' iqn.1986-03.com.sun:01:40503acc01ff.4f86ec2f root@StorageA:~# iscsiadm modify discovery --sendtargets enable root@StorageA:~# iscsiadm add discovery-address 192.168.150.2:3260 - Share physical disks from Storage B (Slave)
NOTE: Please note that disk names are in the form of c0t0d0, but you will have to create LUs overc0t0d0p0. If you receive an error when creating the LU, then you will have to recreate the disk layout by creating a temporary zpool over the drive and then destroy it:zpool create tmppool c4t3d0 zpool destroy tmppool
