Hi Shockneck,
all is in the same datacentre and will be served by the same SAN infrastructure - EMC Symmetrix with Powerpath - Raid5 on the SAN site, dedicated Adapter pairs on the lpar site - no vio except for management purposes.
According to SAN Engineering no problem to make the disks all visible on each node required - even visibility on all 7 nodes is not a problem according to them.
This proposal is for one site only - we will have similar setups for UAT and COB in another datacentre in another country - with database replication between PROD and COB.
Kind regards

pbs_resources_sp2
pbs_resources_sp2(7B) PBS pbs_resources_sp2(7B)
NAME
pbs_resources_sp2 - pbs resources on IBM SP-2
DESCRIPTION
This page summarizes the resources supported by PBS for the IBM SP-2. These resources are specified by including them in the -l option
argument on the qsub or qalter command or in the PBS job script.
RESOURCES
nice The nice value under which the job is to be run. Units: unitary.
walltime
Maximum amount of real time during which the job can be in the running state. Units: time.
arch Specifies the administrator defined system architecture requried. This defaults to whatever the PBS_MACH string is set to in
"local.mk". Units: string.
host Name of host on which job should be run. This resource is provided for use by the site's scheduling policy. The allowable values
and effect on job placement is site dependent. Units: string.
nodes Number and/or type of nodes to be reserved for exclusive use by the job. The value is one or more node_specs joined with the '+'
character, "node_spec[+node_spec...]. Each node_spec is an number of nodes required of the type declared in the node_spec and a
name or one or more properity or properities desired for the nodes. The number, the name, and each properity in the node_spec are
separated by a colon ':'. If no number is specified, one(1) is assumed. Units: string.
The name of a node is its hostname. The properities of nodes are:
. ppn=# specifying the number of processors per node requested. Defaults to 1.
. arbitrary string assigned by the system administrator, please check with your administrator as to the node names and properities
available to you.
Examples:
. To ask for 12 nodes of any type: -l nodes=12
. To ask for 2 "server" nodes and 14 other nodes (a total of 16): -l nodes=2:server+14
The above consist of two node_specs "2:server" and "14".
. To ask for (a) 1 node that is a "server" and has a "hippi" interface, (b) 10 nodes that are not servers, and (c) 3 nodes that have
a large amount of memory an have hippi:
-l nodes=server:hippi+10:noserver+3:bigmem:hippi
. To ask for three nodes by name:
-l nodes=b2005+b1803+b1813
. To ask for 2 processors on each of four nodes:
-l nodes=4:ppn=2
. To ask for 4 processors on one node:
-l nodes=1:ppn=4
. To ask for 2 processors on each of two blue nodes and three processors on one red node:
-l nodes=2:blue:ppn=2+red:ppn=3
host Allows a user to specify the desired execution location. This resource is provided for use by the site's scheduling policy. The
allowable values and effect on job placement is site dependent. Units: string.
other Allows a user to specify site specific information. This resource is provided for use by the site's scheduling policy. The allow-
able values and effect on job placement is site dependent. Units: string.
software
Allows a user to specify software required by the job. This is useful if certain software packages are only available on certain
systems in the site. This resource is provided for use by the site's scheduling policy. The allowable values and effect on job
placement is site dependent. Units: string.
EXAMPLES
qsub -l nodes=15,walltime=2:00:00 script
or in a qsub script as a directive:
#PBS -l nodes=15,walltime=2:00:00
RESOURCE UNITS
The resource values take the following units:
time specifies a maximum time period the resource can be used. Time is expressed in seconds as an integer, or in the form:
[[hours:]minutes:]seconds[.milliseconds]
unitary The maximum amount of a resource which is expressed as a simple integer.
