Solution Type: Sun Alert
Solution 238630 : Installing Solaris 10 Fibre Channel Device Driver
patches without an immediate reboot may cause a System Panic
Bug ID: 6704883
Product
Solaris 10 Operating System
Date of Workaround Release: 11-Jun-2008
SA Document Body
Installing Solaris 10 Fibre Channel Device Driver patches without an
immediate reboot may cause a System Panic
1. Impact
Installing certain Solaris 10 Fibre Channel Device Drivers patches (as
listed below in section 2) may cause a system to panic if installation
of those patches is followed by the installation of certain CD-ROM
Install Boot Image patches without an intervening reboot.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform:
* Solaris 10 with patch 125184-05 (or later) and with patch
119081-25 (or later)
x86 Platform:
* Solaris 10 with patch 125185-05 (or later) and with patch
119082-25 (or later)
For SPARC platforms, this occurs when doing the following:
By first installing patch 125184-05 or later (Solaris 10 Fibre Channel
Device Driver) followed by patch 119081-25 or later (Solaris 10 CD-ROM
Install Boot Image Patch) without a reboot between patch
installations.
For x86 platforms, this occurs when doing the following:
By first installing patch 125185-05 or later (Solaris 10 Fibre Channel
Device Driver) followed by patch 119082-25 or later (SunOS 5.10 CD-ROM
Install Boot Image Patch) without a reboot between patch
installations.
Notes:
1. Solaris 8 and 9 and OpenSolaris are not impacted by this issue.
2. This condition has been seen to occur when installing the SPARC
recommended patch clusters dated prior to 06-June-2008.
3. This issue has not been seen in the x86 clusters which do not have
the patch installation order which triggers this issue.
4. This issue has not been seen in the Sun Alert clusters which
include the Sun Fibre Channel Device Drivers patch at a revision
lower than -05.
5. The panic occurs as a result of the inconsistent fcip(7D) and
fctl(7D) modules loaded in memory.
6. This issue only occurs when installing the two patches one after
the other in the stated order (Drivers patch first, followed by
the CD-ROM Install Boot Image patch) without a reboot in between
the two.
3. Symptoms
There are no predictable symptoms that would indicate the system will
panic prior to patch installation. If the CD-ROM Install Boot Image
Patch is installed after the Sun Fibre Channel Device Drivers patch
without an intervening reboot, the system will panic during or
immediately after installation of the CD-ROM Install Boot Image patch.
4. Workaround
To avoid this issue, install the patches in the correct order, with
the CD-ROM Install Boot Image Patch installed first, followed by a
reboot, before the Sun Fibre Channel Device Drivers patch is
installed.
If the described issue has already occurred, rebooting the system will
restore normal operation. The inconsistency that caused the panic will
have been resolved by the reboot.
5. Resolution
A final resoution is pending completion.
