I have succesfuly set up zfs pool, created block on it , and created iscsi target. The target is visible from esx host and i can us it as datastore.
steps i did:
- zpool create tank raidz2 sdb sdc sdd raidz2 sde sdf sdg
- zfs create -o compression=off -o dedup=off -o volblocksize=32K -V 1500G tank/datastore-ssd
- than i used targetcli to run iscsi target on datastore-ssd
Now i want to add multipath in case of san failure. The problem is that i don't see this device . I am trying to use dm-multipath package and what i need is wwid of device to configure multipath. But i cannot find this wwid. I even don't see this block dev i created as dev. Maybe i am wrong at all and should do it in diffirent way - no idea. Any help would be appreciated.
