Ok, I had iscsi working. Then I umounted the filesystem, and deleted the logical volume, then the RAID, and recreated it with a) 4 more drives (or was it six?), gave it a new RG name, and a new VD name.
I can ping the IP, but can’t rediscover it – just get “no portals found”. I’m finding a fair number of people with this issue, googling, but not a lot of answers. Anyone know what I’ve done wrong?
