Suncluster query
Hello,

I have 2 systems Solaris 10 sparc with latest patches, 2 transports connected and 1 public port each and fiber connections to SAN.

This is first time I am doing a SUN cluster install (latest soft). I installed the software using ./installer and then tried to install using "scinstall" command

Now I find that after configuring the second node, scinstall hangs even though the node is rebooted.(rebooting node .....)

I have already read initial documentation from Sun for Suncluster configuration but now I am confused. Question here is,

What should be the steps taken in order to configure sun cluster on 2 nodes which will be sharing SAN disk?

Do I have to install VxVM before using scinstall or scinstall will detect the SAN disk ? I am sure LUN is assigned for the systems.

I have VxVM product with license (not installed) but no experience on when and how it should be used. Atleast if I come to know when to do which step then I am ready to read any related docuements.

So is it mounting SAN disks to both systems first or is it scinstall first. I tried scinstall first and hung many times. When I retried scinstall, second node is doing kernel panic.

Hope I was able to explain myself here.

Please help!

Thank you...Smilie

whats the Sun Cluster version? Kernel patch level of Solaris 10 on both systems? and OBP , is it updated to the latest?
You can run scinstall w/o installing VxVM first

138888-08 - kernel on both systems, SF v480r
SC version - suncluster-3_2u2-ga.iso
OBP 4.10.7 2003/06/11 07:0 on both systems.

Systems patched to latest.

I wonder why the scinstall hangs after rebooting second node. so even if SAN disk is not configured I can go ahead with scinstall, right? does scinstall detect SAN LUNS or needs to be configured using Sun vol. manager or VXVM?

is there any link anywhere for step by step config? Smilie

Thanks!

any outputs? how does it hang ? due to any firewall?
Might be easier to install them one node at a time, i.e. install the first node and then add a 2nd node to the cluster

also check both nodes on the svcs -xv

you don't need vxvm... but you need somekind of volumemanagement to switch the a filesystem between clusternodes. whre you don't need a volumemanagement is the quorum device.
the question is what kind of cluster (what service is going to be HA) are you trying to install?

Which Storage is attached to the cluster nodes?

The FC ports in the Storage have defined the corrected Flags for SUn CLuster?

For example if you have EMC array, the LUNS must be have the "PER" flag.

Attaching the log.

This time I found while scinstall was rebooting the other node, it hung, then found second was rebooting again and again..

EDIT :

Attaching log from second server,
