Summary: Recreating nim images for HA EMS

Initial Comment:
xCAT Version: Version 2.6.10 (svn r11247, built Wed Dec 14 11:03:02 EST 2011)

This is a procedure issue, not a code issue. But marked high because we are trying to validate this our customers.

The first time I tried HA EMS I configured each nim attribute by hand. When I got to the spot and shared root objects I started to get these messages.

[c250mgrs24-pvt][/mnt/installp/ppc]> /usr/sbin/nim -Fo define -t spot -a server=master -a location=/install/nim/spot/GOLD_71DSN GOLD_71DSN
0042-001 nim: processing error encountered on "master":
   0042-001 m_mkspot: processing error encountered on "master":
   0042-027 m_ckspot: "version" is required to complete the
        definition of the "GOLD_71DSN" object.  This attribute is either
        currently missing or the current operation would cause
        it to become missing.
rc=0
warning: 0042-062 m_ckspot: "GOLD_71DSN" is missing something which is
        required

So during our second HA EMS shot I backed up the nim database and restored it on the new primary server. That seems to work. I'll test it out and if it works then we should schedule a nim backup on the original primary and add it to the script that syncs files.

Kerry,

Creating the spot and shared_root does need different procedure other than
"nim -o define" cmd, I am not sure if we have tried the procedure currently
documented in the HA EMS doc, but if the NIM resources backup and restore
procedure is easier and more efficient, I am fine with updating the HA EMS
doc with the NIM resources backup and restore stpes.

                    Create the spot resource: 

       /usr/lpp/bos.sysmgt/nim/methods/m_mkspot -o -a server=master -a
          location=/install/nim/spot/ -a source=no <osimage>


If the osimage has shared_root resource defined, the shared_root resource
directory needs to be removed before recreating the shared_root resource,
here is an example:

   rm -rf /install/nim/shared_root/71Bshared_root/
   /usr/sbin/nim -Fo define -t shared_root -a server=master -a
location=/install/nim/shared_root/71Bshared_root -a spot=71Bcosi 71Bshared
