AlphaServer SC patch kit:

==========================



AlphaServer SC Version : V2.6 SSB

Kit Name: SCV26SSB4418

Release Date: 01/28/2004

PTR: 153-1-4418

IPMT Number: none

Abstract: panic at pfs_subr.c:2622 when importing node dies



You should not need to reboot any nodes to install this patch nor do

you need to build and deploy new kernels. However, you will need to

take all PFS file systems off line temporarily while installing this

patch because pfs.mod cannot be replaced while it is in use.





Description of Patch:

=====================

A change in the behavior of CFS in Tru64 Unix V5.1B can cause PFS to

panic the other nodes of a cluster when the importing node goes down

unexpectedly for any reason. These particular panics can be

recognised by the following messages in the console log just before

the node goes down:



cmn_err: CE_PANIC: pfs: [os/pfs_subr.c:2622] ASSERT(error == 0)



This patch allows PFS to deal with these new errors and prevents the

panics.









Prerequisites:

==============

This is a V2.6 SSB patch. It will not install on any other version.

Instructions:

=============

This patch is provided as a setld installable kit.  Unpack it

into a directory that is NFS mounted on all domains e.g.

/nfs/SCV26SSB4418 and install it as follows:



Patch required on Management Server (if used) : NO

Patch required on Domains                     : YES



On Domains:

-----------



First, take all PFS file systems offline. They will need to stay

offline for the duration of the installation.



    # pfsmgr offline all



Once this has completed successfully and the PFS file systems are

offline on all nodes (use "pfsmgr show" to check) configure out

pfs.mod like this:



    # scrun -n all /sbin/sysconfig -u pfs



Now install SCV26SSB4418 from the directory you created earlier:



    # cd /nfs/SCV26SSB4418

    # scrun -d all setld -l /nfs/SCV26SSB4418 SCV26SSB4418



There is no need to build or deploy kernels or reboot any nodes.

Finally, configure pfs.mod back in and bring the PFS file systems

back on line:



    # scrun -n all /sbin/sysconfig -c pfs

    # pfsmgr online all



Installation is complete at this point.



    To remove the patch use the following commands:

    # pfsmgr offline all

    (wait for this to finish on all nodes - use "pfsmgr show" to check)

    # scrun -n all /sbin/sysconfig -u pfs

    # scrun -d all setld -d SCV26SSB4418

    # scrun -n all /sbin/sysconfig -c pfs

    # pfsmgr online all
