L700: Changing IBM LTO FC WWN 1

[yelhammar]

While replacing a Fiber Channel IBM LTO1 or LTO2, is there any way to preserve the WWN, so no need to reconfigure the Servers(Solaris 8), JNI driver and to reboot ?

Thanks

YESSSS!!!!!!!!!!!!!!!!! OF COURSE!!!!!

You can change the WWN of your drive in the control panel of your L180 or L700.
This is a normal operation of the CSE of StorageTek.

First. You have to view the WWNN and WWNP of your drive (oldest)

Second. Disconnect the Fiber chanel and put the newest tape drive in the same place and power on.

tirth. In the control panel select "configuration" -- "drive configuration" -- "and select the position of your new drive.

And then you can move the WWWN and the WWNP with the arrows and select number by number.

REMEMBER CHANGE THE WWWN AND THE WWNP, BOTH ARE VERY IMPORTANT.

AND.. (CONTINUE..)

WHEN YOU HAVE FINISHED THE CONFIGURATION, EXIT TO THE MAIN MENU.. SHUT DOWN THE DRIVE.. CONNECT THE FC INTO THE FC PORT OF THE TAPE DRIVE AND THEN POWER ON IT.

....... AND YOU DON HAVE TO RECONFIGURE YOUR HBA, SW OR ANY IN YOUR SAN

BUT..

This not only a WWN issue, you are changing the model of your tape drive, then you have you reconfigure the server, reboot the library (the library have to change thier configuration) and in your storage software you have to define the new drive model...
