It's my understanding that each port a cable could connect to is seen as a seperate controller.

More info; I started with 2 pairs of servers. Each pair of servers had 4 links (2 for each server in the pair) to the same pool of disks (or luns.) So each server in the pair had redundant links to it's set of disks which it shared with the other server in the pair. I want to reduce this to only 1 server (for now,) and give it the right combination of cables from these 2 pairs of servers, so that it will be able to see all the disks from both pools. So I want to plug in each of the 8 cables, and try to determine which of the disks are visible on the other end. If this was scsi, and sparc, I'd use 'probe-scsi-all' from OBP, to see which disks show up on which cables/ports/controllers. What can I use for FC? I discovered 'cfgadm'. And I manged to get it to list the 4 controllers, and 1 disk on each. However the ID of that one disk doesn't look anything like the WWN of the targets I see in /dev/dsk. On top of that why is there is only one disk? I see 18 targets in /dev/dsk, shouldn't I see 18 disks listed mong the 4 controllers? -Kyle > -- Chandan Maddanna > > > This message posted from opensolaris.org > _______________________________________________ > opensolaris-discuss mailing list > [email protected] > _______________________________________________ opensolaris-discuss mailing list [email protected]
