Critical System Protection hot fix

Symantec is releasing a hot fix for the Critical System Protection product to resolve a compatibility issue on the RedHat platform. This hotfix “SCSP-5.2-RHEL-HF1” will work correctly with glibc update version (glibc-2.5.-58.el5_6.4)

RedHat on 6/27/2011 made a glibc patch (glibc-2.5.-58.el5_6.4) available via RedHat Network Update. This is a normal way of receiving updates from RedHat and users would run update process after initial install, scheduled update or automatic update. One of the SCSP programs is not compatible with this version of glibc and causes the agent start to hang the boot-up process

 

Details on the glibc update: http://rhn.redhat.com/errata/RHBA-2011-0901.html


Environment



Affected Critical System Protection Versions: All available SCSP agents running on RHEL 5.x (5.2.5, 5.2.7, 5.2.8)

Affected Operating System: RHEL 5.x (SCSP product does not have the same issue on  RHEL 6 and 6-U1)


Solution



 

If the glibc update has been applied and the system is experiencing a hang state, reboot the system using a suggested method below. Then apply this hot fix and follow the instructions.

If the glibc has not yet been updated, apply this hot fix first and follow the instructions. After the hot fix is applied, you may update the glibc to bring the system up to date with all available patches.

If applying this hot fix is not a viable option at this time, there are a few suggested workarounds below.


How to boot up a hung system successfully:

·         Restart the system, power reset if necessary.
