Installation – Building Block Approach
Take a building block approach
–
Get nodes properly installed
–
Get nodes properly on the network(s)
–
Verify node-to-node rsh/ssh communications
–
Attach disks to servers/nodes and verify
–
Define GPFS cluster
–
Start GPFS and verify all nodes join
–
Create VSDs/NSDs
–
Create file systems
–
Mount file systems

Installation – Node SW and Networks
Get nodes properly installed
Get nodes properly on the network(s)
–
Ensure that the hostnames are resolvable (updated DNS entries or
/etc/hosts entries)
Verify node-to-node rsh/ssh communications
Synchronize all node clocks
–
Use ntp (ntpdate <time_server>)
–
Ease PD
See the GPFS FAQ for the OS being installed to ensure that a supported
OS software is installed.
On Linux there may be a kernel patch. This is documented in the GPFS
Linux FAQ.

Installation – Attach Disks To Servers
Attach disks to servers/nodes and verify
–
Depending on the system/customer requirements, the
disk connection topology will vary.
•
eg. SAN model all nodes are attached to disk
•
eg. NSD model only NSD servers have disk access
–
This setup can be performed without GPFS software
installed on nodes.
–
The recommendations/drivers/SW levels as
recommended by the disk device are used

Installation –Parallel Shell
Install your favorite
–
E.g., the 'dsh' command, psh
−
This is an optional activity but will make the operation of
the cluster much easier.
•
/opt/csm/bin/dsh is in the fileset csm.dsh [AIX]
•
Set the environmental variable $WCOLL to point to a list of
node names.
•
dsh -v date # verify host is up and issue cmd
