I have a two node Red Hat Cluster with HP Proliant servers.
This server has an HP iLO3 for Out-of-band management.
The fence_ilo agent works with iLO and iLO2.
Fence Device and Agent Information for Red Hat Enterprise Linux
You will need to use fence_ipmplan agent with the recommended settings following this Red Hat document:
How do you configure the fence device agent information option for the HP ILO 3?

The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.
Here’s an excerpt:
Madison Square Garden can seat 20,000 people for a concert. This blog was viewed about 64,000 times in 2011. If it were a concert at Madison Square Garden, it would take about 3 sold-out performances for that many people to see it.

I had several logical volumes that were presenting a weird error
root@aix:/ # rmlvcopy lvpooldom01001 1
0516-622 rmlvcopy: Warning, cannot write lv control block data.
I tried to migrate the logical volume off the disk
root@cvrdalebk01:/ # migratepv -l lvpooldom01001 hdisk3
0516-076 lmigratelv: Cannot remove last good copy of stale partition.
Resynchronize the partitions with syncvg and try again.
0516-812 migratepv: Warning, migratepv did not completely succeed;
all physical partitions have not been moved off the PV.
But it was not completed successfully
root@aix:/ # lsvg -l tsm01vg
tsm01vg:

So I ended up removing the logical volumes
root@aix:/ # rmlv lvpooldom01001
Warning, all data contained on logical volume lvpooldom01001 will be destroyed.
rmlv: Do you wish to continue? y(es) n(o)? y
rmlv: Logical volume lvpooldom01001 is removed.
root@aix:/ # rmlv -f lvpooldom01003
rmlv: Logical volume lvpooldom01003 is removed.
root@aix:/ # rmlv -f lvpooldom01004
rmlv: Logical volume lvpooldom01004 is removed.
root@aix:/ # rmlv -f lvpooldom01005
rmlv: Logical volume lvpooldom01005 is removed.
And then recreating them
root@aix:/ # mklv -t raw -y lvpooldom01001 tsm01vg 512
lvpooldom01001
Here is the status. No warning was displayed
root@aix:/ # lsvg -l tsm01vg | grep lvpooldom01001
lvpooldom01001 raw 512 512 1 closed/syncd N/A

Here is a dual port HBA
root@linux:~ # lspci | grep -i fibre

Verifying the WWPN from the HBA
root@linux:~ # cat /sys/class/scsi_host/host0/device/fc_host\:host0/port_name
