Netbackup & VCS - Failing cluster

Tuesday, 23 February 2010 22:07 administrator

If your're Netbackup cluster switches or restarts unexpected, you can find the process causing the switch in :

/usr/openv/netbackup/bin/cluster/AGENT_DEBUG.log

A example:

# grep "Detected process offline" AGENT_DEBUG.log

02/23/10 14:55:091 Detected process offline:nbemm monitor::main
02/23/10 15:00:331 Detected process offline:vmd monitor::main
02/23/10 15:02:331 Detected process offline:nbemm monitor::main
02/23/10 15:42:031 Detected process offline:vmd monitor::main
02/23/10 15:44:031 Detected process offline:nbstserv monitor::main

How to use a LUN larger than 2TB with Veritas Volume Manager (VXVM)

Monday, 09 November 2009 13:44 administrator

If you want to use LUN's larger than 2TB with VXVM on a LINUX host you need to use parted instead of fdiske to create partitions. fdisk is limited to 2TB partitions. The CDS feature is a no-go as well

We assume disk is sdu. Before VxVM can use the disk, it must have a GPT label

# parted /dev/sdu mklabel gpt (the change is instant !!!!)

The default format for vxdisksetup is CDS format, we can't use so we revert to the old format:

# /etc/vx/bin/vxdisksetup -i sdu format=simple

From here it's business as usual :-D

How to use a LUN greater than 2TB on Red Hat Enterprise Linux 4.0 Update 3 with Volume Manager 5.0

Initializing a LUN that is greater than 2TB creates usable space equal to, or less than 2TB with Volume Manager 5.0 on Red Hat Enterprise Linux 4 Update 3 or higher.
