Hello,
i have a problem the configuration of tape devices in a Sun Solaris Fibre
Channel environment. I have the following topology:
2x Sun Solaris E4500 with 2 Emulex FC Adapter in each server
2x Brocade FC Switches (EMC label)
2x EMC CLARiiON FC4700 (two connections to each E4500)
1x EMC DL300 (two connections to each E4500)
1x HP MSL6000 (2x LTO2, 1x FC)
On the DL300 8 devices (IBM LTO2) are configured for each Solaris machine.
The problem is the mapping from the physical device connections to the
logical device names on the Solaris machines:

I have cleaned the path_to_inst file from the "st" entries and made the
following entries in the st.conf.
name="st" class="scsi"
target=0 lun=0;
name="st" class="scsi"
target=1 lun=0;
name="st" class="scsi"
target=1 lun=1;
name="st" class="scsi"
target=1 lun=2;
name="st" class="scsi"
target=1 lun=3;
name="st" class="scsi"
target=1 lun=4;
name="st" class="scsi"
target=1 lun=5;
name="st" class="scsi"
target=1 lun=6;
name="st" class="scsi"
target=1 lun=7;
name="st" class="scsi"
target=2 lun=0;
name="st" class="scsi"
target=2 lun=1;
name="st" class="scsi"
target=2 lun=2;
name="st" class="scsi"
target=3 lun=0;
name="st" class="scsi"
target=4 lun=0;
name="st" class="scsi"
target=5 lun=0;
name="st" class="scsi"
target=6 lun=0;
I also cleaned the /dev/rmt and the /devices/FCADAPTER dirs from "st"
entries. After this i have rebooted the second server with "reboot -- -r".
But the server recreates the same entries after the reboot. Why is the
mapping on the second server different to the first server. The st.conf is
the same on both machines.
I'm not a solaris specialist and i am grateful for every hint.
Thanks in advance!
