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!!

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.

clinfo
clinfo(1M) System Administration Commands clinfo(1M)
NAME
clinfo - display cluster information
SYNOPSIS
clinfo [-nh]
DESCRIPTION
The clinfo command displays cluster configuration information about the node from which the command is executed.
Without arguments, clinfo returns an exit status of 0 if the node is configured and booted as part of a cluster. Otherwise, clinfo returns
an exit status of 1.
OPTIONS
The following options are supported:
-h Displays the highest node number allowed to be configured. This is different from the maximum number of nodes supported in a given
cluster. The current highest configured node number can change immediately after the command returns since new nodes can be dynami-
cally added to a running cluster.
For example, clinfo -h might return 64, meaning that the highest number you can use to identify a node is 64. See the Sun Cluster 3.0
System Administration Guide for a description of utilities you can use to determine the number of nodes in a cluster.
-n Prints the number of the node from which clinfo is executed.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
This is usually because the node is not configured or booted as part of a cluster.
