Solution Type: Sun Alert
Solution 237324 : Solaris 10 patches 128306-03 and 128307-03 may
disable SVM Mirrored Root Systems
Bug ID: 6692047
Solaris 10 Operating System
Date of Workaround Release: 30-Apr-2008
SA Document Body
Solaris 10 patches 128306-03 and 128307-03 may disable SVM Mirrored
Solaris 10 systems using Solaris Volume Manager (SVM) where root is
mirrored may experience multiple services failures (rpcbind(1M),
network/physical) after installing patch 128306-03 (SPARC) or
2. Contributing Factors
These issues can occur in the following releases:
* Solaris 10 with patch 128306-03
* Solaris 10 with patch 128307-03
1. Solaris 10 Update 5 is not affected by this issue.
2. Solaris 8 and 9 are not affected by this issue.
3. Only systems with SVM configured with root mirrored are impacted
by this issue.
To determine if a system has SVM configured with root mirrored, the
following command can be used:
# grep 'rootdev:' /etc/system
If the output contains 'md@', the system is likely affected.
Systems that experience this issue will see multiple services failures
on the order of rpcbind(1M) or network/physical.
This issue cannot be avoided by removing the patches listed. To work
around this issue, a copy of the file "/etc/security/device_policy"
that existed prior to the patch installation needs to be reinstated
after the affected patches have been installed.
1) Prior to installing 128306-03 or 128307-03, a backup should be
taken of the "/device_policy" file. If a backup was not taken, then a
copy can be obtained using the following commands (or use 128307-03
for x86 systems):
# cd /var/sadm/pkg/SUNWcsd/save/128306-03
# uncompress undo.Z
# pkgtrans undo /tmp/all
# compress undo
# cd /tmp/SUNWcsd/reloc/etc/security
# cp device_policy /etc/security/device_policy
# patchrm 128306-03
2) If a different patch backout directory was used during patch
installation by using:
# patchadd -B backout_dir
then that location "backout_dir" needs to be used instead of the
default location as used above (1).
A final resolution is pending completion.
