Date of Workaround Release: 12-Feb-2008

SA Document Body
Solaris MPT(7D) patch May Cause Loss of Devices in NetBackup
1. Impact
Installation of the mpt(7D) HBA driver patch 125081-10 through
125081-16 (SPARC) or patch 125082-09 through 125082-16 (x86) or kernel
patch 127127-11 (SPARC) or 127128-11 (x86) (or installation of the
latest Solaris 10 patch cluster that contains this patch) may cause
lost connections to tape devices, preventing backup operations with
NetBackup.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 10 with patch 125081-09 through 125081-16 or with kernel
patch 127127-11 and without patch 138075-02
x86 Platfom:
* Solaris 10 with patch 125082-09 through 125082-16 or with kernel
patch 127128-11 and without patch 138076-02
Notes:
1. Solaris 8 and 9 are not impacted by this issue.
2. This issue only impacts systems which are running NetBackup using
the mpt(7D) driver for SCSI host bus adapters.
To determine the current mpt(7D) driver version on the system, the
following command can be run:
% modinfo | grep mpt
22 1263020 2bbd0 213 1 mpt (MPT HBA Driver v1.34)
3. Symptoms
After installation of the patch and system reboot, the NetBackup
'/usr/openv/volmgr/bin/sgscan' command no longer sees its tape
devices, and the robot/tape drives in NetBackup are down, as in the
following example:
Before patch application/reboot:
# /usr/openv/volmgr/bin/sgscan

4. Workaround
Do not install mpt(7D) patch 125081-10 through 125081-16 or kernel
patch 127127-11 (SPARC) or patch 125082-09 through 125082-16 or kernel
patch 127128-11 (x86). Do not upgrade to Solaris 10 Update 5. Remain
on, or back down to, patch 125081-08 (SPARC) or 125082-16 (x86).
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 10 with patch 138075-02 or later
x86 Platform
* Solaris 10 with patch 138076-02 or later
