can someone please share their process on how to kernel patch a red hat ent 4 with veritas cluster 5? it's compose of a primary and backup node. the resources are db, disk, nic.
it doesn't need to be detail, just give me the steps like:
login to the backup node and update the kernel
reboot the backup node
check the kernel is updated
failover the cluster and check if the resources are up on the backup node
patch the primary node with the new kernel and reboot
failover it back
Hi Experts,
I wanted to extend a veritas file system which is running on veritas cluster and mounted on node2 system.

I am working with a Sun StoredgeTek 6540 disk array connected to two Sun 490 servers. After taking one of the 490 nodes on the cluster down to single user mode I proceeded to install the latest cluster patch from Oracle. After the patch was completed the system rebooted, failed to rejoin the... (2 Replies)
Yesterday my customer told me to expect a vcs upgrade to happen in the future. He also plans to stop using HDS and move to EMC.
Am thinking how to migrate to sun cluster setup instead.
My plan as follows leave the existing vcs intact as a fallback plan.
Then install and build suncluster on... (5 Replies)

CLUSTER(1) General Commands Manual CLUSTER(1)NAME
cluster - find clusters in a graph and augment the graph with this information.
SYNOPSIS
cluster [-v?] [ -Ck ] [ -ck ] [ -o outfile ] [ files ]
DESCRIPTION
cluster takes as input a graph in DOT format, finds node clusters and augments the graph with this information. The clusters are specified
by the "cluster" attribute attached to nodes; cluster values are non-negative integers. cluster attempts to maximize the modularity of the
clustering. If the edge attribute "weight" is defined, this will be used in computing the clustering.
OPTIONS
The following options are supported:
-Ck specifies a targeted number of clusters that should be generated. The specified number k is only a suggestion and may not be real-
isable. If k == 0, the default, the number of clusters that approximately optimizes the modularity is returned.
-ck specifies clustering method. If k == 0, the default, the modularity will be used. If k == 1 modularity quality will be used.
-ooutfile
Specifies that output should go into the file outfile. By default, stdout is used.
-v Verbose mode.
EXAMPLES
Applying cluster to the following graph,
graph {
1--2 [weight=10.]
2--3 [weight=1]
3--4 [weight=10.]
4--5 [weight=10]
5--6 [weight=10]
3--6 [weight=0.1]
4--6 [weight=10.]
}
gives
graph {
node [cluster="-1"];
1 [cluster=1];
2 [cluster=1];
3 [cluster=2];
4 [cluster=2];
5 [cluster=2];
6 [cluster=2];
1 -- 2 [weight="10."];
2 -- 3 [weight=1];
3 -- 4 [weight="10."];
4 -- 5 [weight=10];
5 -- 6 [weight=10];
3 -- 6 [weight="0.1"];
4 -- 6 [weight="10."];
}
