Mount FIle systems from node-1 onto node-2

Hi,

We have HP UX service guard cluster on OS 11.23. Recently 40+ LUNs presented to both nodes by SAN team but I was asked to mount them on only one node. I created required VGs/LVs, created VxFS and mounted all of them and they are working fine. Now client requested those FS on 2nd node as well.

My queries:

1. Is it possible to mount a VxFS on both nodes at the same time? If yes, what do I need to replicate the VG and LV info from node-1 to node-2?
If no, then we may plan to mount them manually onto 2nd node when 1st node goes down. I guess, for this also, I need to replicate all the VG and LV info from node-1 to node-2?

2. How to configure all the Volumes in cluster mode? There's already one SG package running, can we add these new LVs onto it or should I configure NEW Package to include these volumes? If new package then do I need another IP address to it? what are the tasks would I have to do?

I'm no expert so I would greatly appreciate any help with more details.

Many thanks!!

Need to view all the attributes for a file/node

I need to find out when a file has been created. 'ls -l' just lists the last date the file was modified, not the creation date. I have also noticed when viewing the attributes through NT, the last modified date is the same as the file creation date. I thought maybe this was a fault due to Samba. ...

4S-BACKEND_SETUP(1J)						      4store						      4S-BACKEND_SETUP(1J)

NAME

     4s-backend-setup -- Create a new 4store KB

SYNOPSIS

     4s-backend-setup kbname [--node node-number] [--cluster cluster-size] [--segments segment-count] kb-name

		      --node  Number of this node in the cluster, values range from 0 to cluster-size - 1.  The default is 0.

		      --cluster
			      The number of nodes in the cluster.  The default is 1.

		      --segments
			      The number of segments in the cluster. The default is 2. We recommend one for each CPU core in the cluster as a good
			      starting point. Higher numbers tend to consume more resources, but may result in increased performance.

NOTES

     Once crated with 4s-backend-setup KBs should be started with 4s-backend(1)

SEE ALSO

     4s-query(1), 4s-size(1), 4s-httpd(1), 4s-backend(1), 4s-delete-model(1)

EXAMPLES

     $ 4s-backend-setup --node 0 --cluster 1 --segments 4 demo

     Creates the indexes for a single-machine KB with four segments, named "demo".
