Hi, I am new here:)
I have a big issue here: There are 2 servers (Sun M5000, one production and one backup), 2 Brocade switches (3800) and a StorageTek 6540 array. Current SAN includes the array, switches and the production server. I am now trying to make the backup server join the SAN. After I added two new zones (Each contains one port in the array and one port in the backup server) to the active configration of the two switches, the connection between the production server and the array was lost. Production server name is prdserver and backup server name is bpserver. The following is some info. Please help and thank you much in advance!
On switch 1:

After the array disconnected from the production server, I have to unplug the cables connecting the new server to switches. The following is the current information:

--->>>After I added two new zones (Each contains one port in the array and one port in the backup server) to the active configration of the two switches, the connection between the production server and the array was lost.
after cfgsave and commit, you must enable/start the config.
12-21-2011 05:25 AM
I did run cfgenable. Please see the procedure above.
No matter the modification is enabled or not, how could the existing server lose connection to the array?
12-21-2011 05:47 AM
Perhaps, but I'm guessing, the zones for your production server was removed from the active config, cfgsaved but not cfgenabled.
After a while you add new zones save again and enable the config with production zone gone.
But that depends on how you fixed the production servers. If a rescan for HW changes/ioscan or whatever fixed it above statement will most likely not be the case.
12-21-2011 06:09 AM
After I unpluged the cables connecting to the secondary server from the switches and rebooted the production server, everything returned to normal.
So, the zone for the production server is saved.
12-21-2011 08:28 AM
Maybe its an copy paste error but i noticed the alsia of the bp server in both configs is odd.
cfg: Switch
alias: bpserver_HBA_port1
21:00:00:1b:32:84:fe7
and
cfg: switch1
alias: bpserver_HBA_port3
21:00:00:1b:32:84:178
They both miss a character and a colon.
12-21-2011 09:08 AM
Yes. They were missing during copy and paste. Here are the current settings:
cfg: Switch
alias: StorageTek_6540_port_A2
20:24:00:a0:b8:47:93:c8

12-21-2011 09:16 AM
To bet would be nice if that solved your problem.
-What happens if you reconnect one cable?
-What messages (event messages on the switch) did you get the forst time.
-Did you try a fcping between production host and storage and/or backup host and storage to rule out any zoning issue?
12-21-2011 12:02 PM
We can't do tests on the critical production server. Old version of FabricOS does not have fcping command. What is the best way to get error log or event messages?
