May Cause the Solaris System to Panic or Become Inoperable
Bug ID: 6586286
Solaris 10 Operating System
Date of Resolved Release: 19-Mar-2008
SA Document Body
Solaris 10 MPT Driver Patch For Newer SAS Chipset May Cause the Solaris
System to Panic or Become Inoperable
Solaris 10 systems with a Sun StorageTek PCIe SAS Host Bus Adapter
(HBA) and Solaris 10 MPT(7D) driver patch 125081-09/-15 (SPARC) or
125082-09/-15 (x86) installed may experience a panic during boot or
shortly thereafter. If the boot device is connected to the SAS HBA,
the system may become inoperable.
2. Contributing Factors
This issue can occur in the following releases:
* Solaris 10 MPT Driver patch 125081-09 through 125081-15
* Solaris 10 MPT Driver patch 125082-09 through 125082-15
for the following platform:
* Sun StorageTek PCIe SAS Host Bus Adapter (SG-XPCIE8SAS-E-Z) with
firmware revision 1.23.04 or higher.
1. Solaris 8 and 9 are not affected by this issue, as the SAS HBA
listed (and its chipset) is not supported prior to Solaris 10.
2. The system may still experience a panic from this issue if the
above HBA is installed on the system with the patches listed,
regardless of whether or not the HBA is connected to a boot
Solaris will panic or become inoperable during the mpt(7D) attach
process, during boot, or soon thereafter.
There is no workaround for this issue. Please see the Resolution
This issue is addressed in the following releases:
* Solaris 10 with MPT Driver patch 125081-16 or later
* Solaris 10 with MPT Driver patch 125082-16 or later
Note: In addition to specific patch instructions stated in the patch
README, one of the following actions (in order of preference) must be
taken in order to apply the patch. Not all options may be feasible
depending on your configuration.
A) Boot with the affected SAS cards removed from the system, then
apply the patch fix using the normal procedures before replacing the
B) Boot Solaris from an alternate device which does not contain one of
the affected patches, mount the affected root device in a
separate directory (e.g., /a), then apply the patch fix to the
affected installation using the 'patchadd -R <mount_point> <patch>'
C) Temporarily replace the affected SAS cards with one or more SAS
cards that contain older firmware/chipset (375-3487-01), then apply
the patch fix using the normal procedures (may require additional
assistance from Sun Support).
