Oracle HSM - Some Drives Went Down and Not Coming Online

(Doc ID 2296064.1)

Last updated on AUGUST 15, 2017

Applies to:

Oracle Hierarchical Storage Manager (HSM) and StorageTek QFS Software - Version 4.0 to 6.1 [Release 4.0 to 6.0]
Information in this document applies to any platform.


The site has tape drives shared between two MDS. Two of the drives went down on host MDS-4 due to I/O errors:

Drive was set to unavailable in MDS-4, a tape was loaded and 'mt -f status' command returned Drive busy.
The same set of actions was done on the other MDS and it was able to run the mt command successfully. It looks like the other MDS has some kind of lock on the drive.


SAN errors showed up unexpectedly
