Solution Type: Sun Alert
   Solution  237324 :   Solaris 10 patches 128306-03 and 128307-03 may
   disable SVM Mirrored Root Systems          
   Bug ID: 6692047

   Product
   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
   Root Systems

1. Impact

   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
   128307-03 (x86).

2. Contributing Factors

   These issues can occur in the following releases:
   SPARC Platform
     * Solaris 10 with patch 128306-03

   x86 Platform
     * Solaris 10 with patch 128307-03

   Notes:
    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.

3. Symptoms

   Systems that experience this issue will see multiple services failures
   on the order of rpcbind(1M) or network/physical.

4. Workaround

   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
       # reboot
       # metasync
   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).

5. Resolution

   A final resolution is pending completion.
