Hi all,
I am playing with iscsi_initiator on FreeBSD 7-STABLE and Dell
PowerVault MD3000i. This is the first time I am testing iSCSI...
[...]
If I setup RAID 5 'Disk Group' consisted of 4x 1TB SATA drives (in
MD3000i) and then created for example 2 'Virtual Disks', both are
detected by iscontrol and added to /dev/ as da0 and da1, but da1 spams
log with messages like this:
[...]
I use MD300i with FreeBSD 7.0 and 7.1 with iscsi-2.2.2. It work fine.
But be careful to configure MD3000i. MD3000i assign by default first
disk to preferred controller 0, second disk to preferred controller 1,
third disk to preferred controller 0, and so on. First, third, fifth...
disks is usable from FreeBSD, but second, fourth,... disks result unusable.
Work around: manually assign all disks to controller 0.
I'm talking with Dell's technical support, but Dell not support FreeBSD!
In any case, technical support tell me, the problem (maybe) is the
multipath. FreeBSD use only one path (only one IP) to communicate to
MD3000i. Second net interface in unused.
I hope that I have been helpful.
