Yes, did similar things more than once on different
OSes and your procedure looks like ok !

Verify just tape device naming to be consistent between both
servers and/or adapt changer path if path is not same [email protected]
addr. Compare using inquire output (/etc/LGTOscsi/inquire if I am right)

I would just add : 

* save res and mm directories (to a tar or zip) before starting
networker on its new home (with nsrd down). In case of trouble 
with lics or DNS settings that may corrupt resdb, then you will be
faster back on track. And unmount all volumes from all devices
(excepted file or Adv_file devices) before shutting down networker.

* force a bootstrap on an empty tape (or with no other backup).
If you have to recover from mminfo or scan the tape, it will be
faster. If your indexes are not to big, force also a full 
index backup. (create a temp group, define all your clients as
member of that group, define the temp group in a pool (if it is the
case)). 
Then launch manually one or more tape mount in correct
pool on your backup server and launch
        savegrp -O -l full -N <wanted parallelism> <TMP_GRP_NAM>
Set with -N <wanted parallelism> as "-N 8" or "-N 10" depending
how many devices you will be using (best is sum your per device target
sessions) to have more devices being writing.

Once finished, unload all of the backup server tapes, 
force a bootstrap (savegrp -O -l full -c <backup server> <TMP_GRP_NAME>)
after having manually loaded and relabelled a recyclable tape or loaded
an empty one (to be sure networker to use that tape as no mount request
to perform, volume being already mounted )
 
Good luck,

TH

Hi,

 

We're planning an upgrade of the operating system on our NetWorker
server from Solaris 9 to Solaris 10.  We also will be moving the NW
server to new hardware.  My plan is to do both steps at once like this:

 

-          Set up new server running Solaris 10

-          Install NW server software

-          Unmount /nsr (on a SAN disk) from old NW server running
Solaris 9

-          Change hostnames/IP addresses so that the name/IP of the
backup server does not change

-          Adjust SAN zones so new server has access to disk 

-          Adjust SAN zones so new server has access to the tape library

-          Mount /nsr onto new NW server running Solaris 10

-          Bring up NW and test

 

The same NetWorker version (v7.2.2) will be used on both servers and
I'll be doing a host transfer for the licenses.  Does anyone see any
problems with this procedure?  Has anyone done anything similar?  

 

Thanks.

Teresa
