SUMMRY (Maybe): Adding 9840 Drives
2007-12-24 21:30:00
rebooted Switch Nr 3. That made Solaris see the new Tape drives. I have
yet to check that it works, but the links are now being created.
Can anyone however tell me how I can map a /dev/rmt/? entry back to a
portname or wwn ?
Thanx,

Original question follows.
Hi all,
I'm busy working on a new SAN to be used for Backups of multiple platform
systems, and for both backups and Disk connectivity for Solaris systems.
Right now I am trying to connect the first system, a Solaris machine
running the NetBackup Master, to the new SAN.
The SAN currently consists of:
3 x 16-port Silkworm Brocade switches connected in a triangle.
2 connections to HDS, one each from Switch 1 and 2.
2 connections to the NetBackup master system, one each from Switch 1 and 2
1 x 9840 drive on Switch 1.
5 x 9840 drives on Switch 3.
The machine has got 2 fcaw controllers. There are 4 paths to each of the 2
HDS JBOD luns because there is 2 ports used on the HDS. Also there is 2
paths to each tape drive (one Fabric port to each drive, but seen via both
JNI controllers.
I can see the devices on switch 1 and 2 with no problem, both via either
fcaw 0 or 1, so the Inter-switch link is functional as well.

However I can not see any devices on Switch #3. Currently, the nsshow
command knows about 5 drives.
There is a zone for tape drives and a zone for the HDS ports. Both ports
of the Unix system is in both zones.
I'm guessing my problem lies with sd.conf and st.conf settings.
Whatever I do, a touch /reconfigure creates only the following 2 links in
/dev/rmt
# ls -l /dev/rmt/?
lrwxrwxrwx 1 root root 40 Dec 24 10:23 /dev/rmt/0 ->
..http://devices/sbus at 6d,0/fcaw at 0,0/st at 1,0:
lrwxrwxrwx 1 root root 40 Dec 24 10:24 /dev/rmt/1 ->
..http://devices/sbus at 6d,0/fcaw at 1,0/st at 2,0:
my st.conf looks like this
name="st" class="scsi" target=0 lun=0 port=0115E0;
name="st" class="scsi" target=1 lun=0 port=0312E0;
name="st" class="scsi" target=2 lun=0 port=0313E0;
name="st" class="scsi" target=3 lun=0 port=0314E0;
name="st" class="scsi" target=4 lun=0 port=0315E0;
name="st" class="scsi" target=5 lun=0 port=0311E0;
name="st" class="scsi" target=6 lun=0 port=0115E0;
name="st" class="scsi" target=7 lun=0 port=0312E0;
name="st" class="scsi" target=8 lun=0 port=0313E0;
name="st" class="scsi" target=9 lun=0 port=0314E0;
name="st" class="scsi" target=10 lun=0 port=0315E0;
name="st" class="scsi" target=11 lun=0 port=0311E0;
name="st" class="scsi" target=6 lun=0;
name="st" class="scsi" target=7 lun=0;
name="st" class="scsi" target=8 lun=0;
# This line adds support for Fibre Channel Tapes
name="st" parent="fp" target=0;
It does appear as if the port=XXXXXX bits are ignored. From the device
links it appears that always fcaw0 Target 1 LUN 0 and fcaw1 Target 2 LUN 0
are created, and from /var/adm/messages I gather these link to port=0115E0
no matter what I try.
Any suggestions!?
Thanx,

P.S. This is urgent because our backups are currently overrunning their
allocated window!
P.P.S There are no Directly attached tape drives on this UNIX system. I
have been told that accessing tape and disk across the same fcaw port is
problematic, but that doesn't seem to be the case. I am worried about the
choice of target and lun numbers, however, because the disk luns on C2 and
C3 are on target 1 and 2, both LUN 0 and 1. I am using Solaris 8 with
Kernel Patch 108528-08 and JNI fcaw driver 2.5.8.HIT.07
P.P.P.S The Disk access works 100%. The tape drive access has yet to be
confirmed. For now I trust that if a device link for a tape devices is
created, it is working.
