Patch: update-is931014 built on 25May18-13:51:43

Product: VTL v8.20 Build 9310

Areas Affected: Tape, iSCSI, Memory, Log, CLI

Prerequisite: update-is931012

Behavior: Interruptive; stops the server modules if running, copies binaries, and restarts the server modules.

Mandatory for:
- All new installations
- Next time maintenance is performed on existing installations
- Servers experiencing issues related to affected areas


FIXES:
------
Tape:

- Symptom: Overwriting a deduplicated tape via Tivoli Storage Manager (TSM) fails.

- Cause: The tape block information was not correctly retrieved after starting inline deduplication when ALLOWOVERWRITE was set by TSM.

- Resolution: Correctly get the tape block information for inline deduplication.

- Severity: Medium

- Files: tlecore.ko

- References: TS311178 BZ2111





- Symptom: A kernel error occurs when the VTL database has a mirror and there are many concurrent backup jobs.

- Cause: A mirroring thread was scheduled on a CPU while it was already running on another CPU.

- Resolution: Do not schedule a thread if it is already running.

- Severity: Medium

- Files: kipstor.ko

- References: TS310671 BZ2001





- Enhancement: Automatically move a tape from a standalone drive to the vault when the backup software ejects the tape.

- Resolution: Provide an option to move a tape to the vault after ejecting the tape. To enable this option, run: 'echo allowtomovetapefromsatovault=1 >/proc/tle'.

- Severity: Low

- Files: tlecore.ko

- References: RFE2261 BZ2181





- Enhancement: Prevent the 3203 and 9210 warnings for an LTO7 tape on IBM i series.

- Resolution: Remove inquiry page 0xE0 from LTO7 tape emulation on IBM3580 tape drives.

- Severity: Low

- Files: tlecore.ko

- References: RFE2421 BZ2154





iSCSI:

- Enhancement: Optimize backup speed with inline deduplication thru 10 Gb iSCSI connections.

- Resolution: Update the iSCSI target module to leverage memory for inline deduplication.

- Severity: Low

- Files: tlecore.ko fsiscsi.ko

- References: RFE2430 BZ2167





Memory:

- Symptom: Memory usage of the server keeps increasing slowly.

- Cause: There was a small memory leak when performing post-deduplication and replication.

- Resolution: Release all allocated memory.

- Severity: Medium

Log:

- Symptom: The system log displays a 'cannot get file' message.

- Cause: A file was temporary unavailable.

- Resolution: Add retry logic to access the file.

- Severity: Low

- Files: ipstorcomm

- References: TS311698 BZ2269





CLI:

- Symptom: The CLI command 'exportvirtualtape' to export a tape fails when the tape is configured with replication after deduplication.

- Cause: There was an invalid check for replication.

- Resolution: Remove the invalid check.

- Severity: Low
