WWN number disappearing and reclaiming within a minute.
-------------------------------------------
1/0/8/1/1: Device at device id 0x620f6c has disappeared from Name Server GPN_FT
(FCP type) response, or its 'Port World-Wide Name' has changed.
device id = loop id, for private loop devices
device id = nport ID, for fabric/public-loop devices
System won't be able to see LUNs behind this port.
1/0/8/1/1: Device at device id 0x620f6c is back in Name Server GPN_FT (FCP type)
response, and its 'Port World-Wide Name' remains the same as
original.

Re: WWN number disappearing and reclaiming within a minute.
First, for zoning purposes, each port can only be connected back to your switch/director to a single port. Hence your Ultrium tape drive's HBA port would be connected to it's own switch port. And your disk (SAN disk) would be connected to it's switch port. Generally tape drives are only connected to a single fabric, while disk arrays and servers are dual connected, each down it's own respective fabric's switch/director. That is if you have a dual fabric environment, which is not required, but highly recommended.
If your server and disk are okay, as you say, then my guess is somebody has zoned the tape library incorrectly. But that's a big, shooting in the dark, guess.
So my suggestion is to ask that your SAN Administrator take a look at their zoning and confirm it first.
Just a thought,
Rita

Re: WWN number disappearing and reclaiming within a minute.
Another thing is you should talk with backup admins that are there any problem with tape,any reboot issue...

The drivers are not the lasted..but they are the same for other card as well..and no issues are faced there..

Re: WWN number disappearing and reclaiming within a minute.
Your problem then may be hardware.
Maybe a bad cable or a bad port.
Rgrds,

Re: WWN number disappearing and reclaiming within a minute.
I think there is either a bad cable/port or the zoning is not consistent or correct on the SAN.
If it is zoning, other systems in the same or nearby zone should have similar problems.

Re: WWN number disappearing and reclaiming within a minute.
Adapter at hardware path 1/0/8/1/1 : Target device is back. Port
World-wide name remains the same as original.
Description of Error:
lbolt value: 549233732
Target with device id 0x620f6c is back in the Name Server GPN_FT (FCP type)
response. And the 'Port World-wide name' remains the same as original.
device id = loop id, for private loop devices
device id = nport ID, for fabric/public-loop devices
Probable Cause / Recommended Action:

Re: WWN number disappearing and reclaiming within a minute.
what device is attached to Port 15 of the SAN Switch with Domain ID 98? (0x620f6c)
My guess is that it's a Tape Device, (the 6c sounds like a loop ID, disk devices usually have 00 as the last digits) What sort tape device is it? (Library Type, Manufacturer)
Check the SAN port. Are many link failures on that port? Is the tape drive going intermittently offline?
We have a similar error occuring. No idea why. A tape device loses its SAN connection, and comes back up 30 seconds later.
Regards,
Stephen

Re: WWN number disappearing and reclaiming within a minute.
Will updating the latest STM version improve the situation. I would prefer that than disabling the alerts
