hacmp in a 7 node configuration ?

Hi Guys,

I have to design a multinode hacmp cluster and am not sure if the design I am thinking of makes any sense.
I have to make an environment that currently resides on 5 nodes more resilient but I have the constrain of only having 4 frames. In addition the business doesnt want to pay for more lpars than they have to. So I would like to go for a 5 active + 2 spare cluster with following setup:

Quote:
F1: A1 + A2
F2: A3 + S1
F3: A4 + S2
F4: A5

A1 could failover to S1
A2 could failover to S2
A3 could failover to S2
A4 could failover to S1
A5 could failover to S1 or S2 (this is the most important environment).
A1 has higher need in resources so I would give S1 the same amount of resources A1 has and all others need about half as much resources, so S2 would have their amount.

Do I have to make all storage (about 3-5 TB / lpar) visible to all nodes or just to the nodes that are intended to takeover the resources.

Does this sound sensible or do I forget anything in this setup? Does anyone maybe run a similar setup and can share his experiences?

I appreciate your comments.

Kind regards
zxmaus

NAME
cmviewconf - view Serviceguard cluster configuration information SYNOPSIS
cmviewconf [-o output_file] DESCRIPTION
cmviewconf collects and displays the cluster configuration information, in ASCII format, from the binary configuration file for an existing cluster. Optionally, the output can be written to a file output_file. This command can be used as a troubleshooting tool to identify the configuration of a cluster. To view cluster information, a user must be superuser(UID=0), or have an access policy of MONITOR allowed in the cluster configuration file, or have a policy of PACKAGE_ADMIN in a package's configuration file. See access policy in cmquerycl(1m) or cmmakepkg(1m). NOTE: When this command is run by an authorized user who is not the superuser(UID=0), only those entries that match the user running the command and the node where the command is run are displayed. Options cmviewconf supports the following options: -o output_file Log configuration information to a specified output file. If this option is not specified, the information will be directed to stdout. RETURN VALUE
cmviewconf returns the following value: 0 Successful completion. 1 Command failed. EXAMPLES
To dump the contents of the binary configuration file to the file /tmp/viewconf.log: cmviewconf -o /tmp/viewconf.log To dump the contents of the binary configuration file to the screen: cmviewconf AUTHOR
cmviewconf was developed by HP. SEE ALSO
