Steps 1 to 17 to configure HACMP

Steps to configure HACMP:

1. Install the nodes, make sure the redundancy is maintained for power supplies, n/w and
fiber n/ws. Then Install AIX on the nodes.
2. Install all the HACMP filesets except HAview and HATivoli.
Install all the RSCT filesets from the AIX base CD.
Make sure that the AIX, HACMP patches and server code are at the latest level (ideally
recommended).
4. Check for fileset bos.clvm to be present on both the nodes. This is required to make the
VGs enhanced concurrent capable.
5. V.IMP: Reboot both the nodes after installing the HACMP filesets.
6. Configure shared storage on both the nodes. Also in case of a disk heartbeat, assign a
1GB shared storage LUN on both nodes.
7. Create the required VGs only on the first node. The VGs can be either normal VGs or
Enhanced concurrent VGs. Assign particular major number to each VGs while creating
the VGs. Record the major no. information.
To check the Majar no. use the command:
ls –lrt /dev grep
Mount automatically at system restart should be set to NO.
8. Varyon the VGs that was just created.
9. V.IMP: Create log LV on each VG first before creating any new LV. Give a unique
name to logLV.
Destroy the content of logLV by: logform /dev/loglvname
Repeat this step for all VGs that were created.
10. Create all the necessary LVs on each VG.
11. Create all the necessary file systems on each LV created…..you can create mount pts
as per the requirement of the customer,
Mount automatically at system restart should be set to NO.
12. umount all the filesystems and varyoff all the VGs.

13. chvg –an ---All VGs will be set to do not mount automatically at
System restart.
14. Go to node 2 and run cfgmgr –v to import the shared volumes.
15. Import all the VGs on node 2
use smitty importvg -----import with the same major number as assigned on node
16. Run chvg –an for all VGs on node 2.
17. V.IMP: Identify the boot1, boot2, service ip and persistent ip for both the nodes
and make the entry in the /etc/hosts.
