I've had a case open with EMC on this for 2 months (21208694) with no resolution yet. I'm hoping for better luck here.
I have a RHEL4 Update 4 64bit server (SRV1) and a storage node (SN1) each with the same type of jukebox (Qualstar 4480 with four AIT-4 drives) , OS, and version of Networker 7.3.3 Build 510. All clients have 7.3.3 build 510 as well. Both have 2 network connections and all clients have both addresses in their host tables and aliases in their configuration. Both nodes look correctly configured and seem to work well within the NMC. Many of the clients also have 2 network ports and can reach both nodes on either port (one gigabit, one 100baset).
The problem is that the clients will only write to tapes in the node that is in the top of the storage node field in the client config. IE, if nsrserverhost (SRV1) is alone or on top of the list (I know it's supposed to be on bottom only) all save operations go to tapes in SRV1 only. If SN1 is above nsrserverhost in the storage node conf field, all saves go to tapes in SN1 only. If I do reverse the order, the saving then works in the reverse manner.
But, at the end of every savegroup session, it seems to require an available tape from that pool in the other non-saving node (second in list) to write the bootstrap or index info (I assume). So it can write to tapes in both nodes, but will not save sets to both, only one. Also, restores work from either node just fine. All jukebox operations work to both nodes as well.
I have had to revert back to the oldauth (or noauth) on both nodes as I was getting many authentication errors. That eliminated those errors.
I have noticed many times that the nsrlcpd keeps restarting itself and SN1 gets the message that it is "no longer managed by nsrlcpd". The nsrmmd daemons on SN1 keep restarting an average of 5 times each day. It seems to do it more with increased backup activity.
I have placed both SRV1 and SN1 in each client's (and SRV1 and SN1) /nsr/res/servers file but made no difference. I also tried placing the names of the 2nd ethernet interface on both SRV1 and SN1 in that file without luck. What should be in this file and what shouldn't.
I have tried placing all the aliases of hostnames and 2nd ethernet hostnames in the aliases field in the SN1 and SRV1's config. Also I place FQHN's in there if DNS problems are the cause.
I also am not sure what should go in the storage node fields in the client config of SRV1 and SN1, the same as all the clients with both nodes, or just the SN1 node name?
I have turned off all firewalling/iptables without luck as well.
I have one of the better support guys at EMC , but it's very hard to contact him and even worse to try and make webex work (only works with XP now, not with any linux/unix) which is what they always require. Powerlink is horrible IMO and I've got much better results searching here.
Thanks in advance!
