Patch Installation Instructions:
--------------------------------
Please refer to the man pages for instructions on using 'patchadd'
and 'patchrm' commands provided with Solaris.
The following example installs a patch to a standalone machine:
example# patchadd /var/spool/patch/123456-07
The following example removes a patch from a standalone system:
example# patchrm 123456-07
For additional examples please see the appropriate man pages. Any
other special or non-generic installation instructions should be
described below as special instructions.
Special Install Instructions:
-----------------------------
NOTE 1: ldc_dtsb_hit() stores VA_MAP before the LDC_VA (bug 15816287):
SPARC T3 and SPARC T4 systems running Oracle VM Server for SPARC:
domain with a virtual network device or a virtual switch under
heavy stress might panic in rare circumstances.
The solution is to update the system firmware to version 8.3.0.c
or later.
NOTE 2: To get the complete fix for 15747988 (reset primary-vsw net-dev
value caused host panics in loop), please also install the
following patch:
