Technical data

The patch README provides instructions on which patches require a reboot.
Note – Sun strongly recommends that patch operations are carried out in a single-user mode,
especially when this is recommended by the patch README.
If you are running non-global zones or have lofs disabled, consider the following points when
installing or removing deferred-activation patches:
■
All non-global zones must be in a halted state for this patch operation. You must halt the
non-global zone before applying the patch.
■
Deferred-activation patching requires the loopback le system, lofs in order to complete
successfully. Systems running Sun Cluster 3.1 or Sun Cluster 3.2 are likely to have lofs
turned o because of restrictions on HA-NFS functionality when lofs is enabled. Therefore,
before a deferred-activation patch is installed, you must re-enable the loopback le system
by performing the following steps.
1. Remove or comment out the following line in the /etc/system le:
exclude:lofs
2. Reboot your system.
3. Install the patch.
4. After you have completed the patch installation operation, restore or uncomment the
same line from the /etc/system le.
5. Reboot the system to resume normal operations.
No error message is displayed.
Workaround: Sun recommends Solaris Live Upgrade to manage patching. Solaris Live
Upgrade prevents the problems of patching a running system. Solaris Live Upgrade reduces the
amount of downtime involved in patching and reduces risk by providing fallback capability if
problems occur. For more information, see

Possible Error With 32-bit Applications Getting File
System State on Large File Systems (6468905)
When run on large le systems, for example ZFS, applications using statvfs(2) or statfs(2)
to get information about the state of the le system exhibit an error. The following error
message is displayed:
Value too large for defined data type
Workaround: Applications should use statvfs64() instead.
