Error description
Lanfree backup to a virtual tape library, where libtype=VTL, that does not properly emulate the drive feature Append-Only mode, can fail with: ANR8302E (Session: 26, Origin: STANAME) I/O error on drive DRIVE0 (/dev/rmt0) with volume 123456L5 (OP=ALLOWOVERWRITE, Error Number=22, CC=0, rc = 1, KEY=05, ASC=24, ASCQ= 00) This same failure can also be seen on the server if the library is defined as a SCSI library type. However, if the library is defined as a VTL library type on the server, the error will not surface, because the server incorrectly fails to utilize the drive feature Append-Only mode. Please note that if the virtual tape library correctly emulates the Append-Only mode, there is no issue regardless of configuration. VTL's that do not emulate or support the Append-Only feature need to use TSMONLY for the CHECKTAPEPOS option on all servers and storage agents using the library. Tivoli Storage Manager Versions Affected: 6.3.x Initial Impact: Low Additional Keywords: TSM
Local fix
Set CHECKTAPEPOS option to TSMONLY on all servers and storage agents using the library.
Problem summary
**************************************************************** * USERS AFFECTED: All Tivoli Storage Manager server users with * * * * a virtual tape library (VTL) that emulates * * IBM LTO Generation 5 tape drives or later. * **************************************************************** * PROBLEM DESCRIPTION: See ERROR DESCRIPTION * **************************************************************** * RECOMMENDATION: Apply fixing level when available. This * * problem is currently projected to be fixed * * in levels 6.3.5 and 7.1.1. Note that this is * * * * subject to change at the discretion of IBM. * **************************************************************** *
Problem conclusion
This problem was fixed. NOTE: When this fix is applied, the LOCAL FIX may still need to be applied until the VTL library correctly emulates the Append-Only mode drive feature. Affected platforms: AIX, HP-UX, Solaris, Linux, and Windows.
