Do you have any SAN link issue ?

[MKR_1]

No

[點燃]

I dont think there is some thing to be woried about. You may have HP h/w engineer check your HBA'a once?

[Larry Klasmier]

Are all the tape drives doing this or only certain ones?

[Patrick Wallek]

SCAN means another ioscan operation is running.

From the ioscan man page:
SCAN
a scan operation is in progress for this node

If you see the status of scan, check the process table and see if there is another ioscan running.

ps -ef |grep ioscan

[Torsten.]

As said above, SCAN means another ioscan is running currently (either from another user/session or from diagnostics.

Some minutes later you should get a different status - try again.
