Greetings from Mexico City...
We install a SunFire V490 with two 2 GB HBA adapters in slots 0 and 1,
we also have a 3510 disk array with 8 * 146 gb hard drives in RAID5. We
create 2 disk groups
DG0 -- 4 Disks
DG1 -- 3 Disks
One disk for global spare1
We use channel 0 and channel 5 in the disk array, we map the DG0 as
primary in channel 0 and primary in channel 5 and DG1 as secundary in
channel 0 and 5, if we plug the HBA in slot 0 we saw the two DG4s in the
format command output, we saw the same if we plug the HBA in the
slot1. The format output looks like this:
c1t0d0
c1t1d0
c2t40d0
c2t41d0
c2t46d0
and here's the questions:
1.- If we plug in the two HBA at the same time and tape format command
we will see 4 disk4s?
2.- If so, we can install some software like traffic manager in order to see
only 2 disks, is that possible?
3.- If its possible, if one of my connections felt down we can access to
both disks by using the other connection?
TIA
