HP Serviceguard Extended Distance Cluster for Linux A.12.00.00 Deployment Guide, March 2014

IMPORTANT: It is recommended that you maintain an equal number of nodes at both sites during
maintenance.
Configuring the RAID Monitoring Service
By default, RAID monitoring service is available as part of the package configuration file. If you
need to configure more than one serviceguard-xdc package running in the same cluster, edit the
service_name field as service_name. It must be unique for all the packages running on same
Serviceguard cluster. In case of VxVM mirroring, RAID monitor script monitors the active plexes
available in the mirrored volume.
NOTE: Before applying the package configuration, check cat/proc/mdstat output to ensure
that the MD device that you have specified in the package configuration, is not active. If active,
then stop the MD device as described in step 2, Creating a serviceguard-xdc Modular Package.
Stopping Autostart of the MD Device
To stop autostart of the MD device on reboot:
1. Add raid=noautodetect in /boot/grub/grub.conf or /boot/grub/menu.lst file.
Following is an example of what the /boot/grub/grub.conf or /boot/grub/menu.lst
file contents looks like:
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux Server (2.6.32-279.el6.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.32-279.el6.x86_64 ro root=UUID=65323756-38f9-4b1d-8f2a-41ee45d53fdc
rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 rhgb crashkernel=auto
KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM raid=noautodetect
initrd /initramfs-2.6.32-279.el6.x86_64.img
2. Delete or move the 64-md-raid.rules and 65-md-incremental.rules file from
/lib/udev/rules.d directory to any /tmp directory.
NOTE: You must perform these steps on each node in the cluster.
