Configuring your Environment for Software RAID

Configuring the Package Control Script and RAID Configuration File

Configuring the Package Control Script andRAID Configuration File

This section describes the package control scripts and configuration files that you need to create and edit to enable Software RAID in your Serviceguard environment.

Earlier versions of Serviceguard supported MD as a multipathing software. As a result, the package control script includes certain configuration parameters that are specific to MD. Do not use these parameters to configure XDC in your environment. Following are the parameters in the configuration file that you must not edit:

#MD (RAID) CONFIGURATION FILE

#Specify the configuration file that will be used to define

#the md raid devices for this package.

#NOTE: The multipath mechanisms that are supported for shared storage

#depend on the storage subsystem and the HBA driver in the

#configuration. Follow the documentation for those devices when setting

#up multipath. The MD driver was used with earlier versions of

#Serviceguard and may still be used by some storage system/HBA

#combinations. For that reason there are references to MD in the template

#files, worksheets, and other areas. Only use MD if your storage systems

#specifically calls out its use for multipath.

#If some other multipath mechanism is used (e.g. one built

#into an HBA driver), then references to MD, RAIDTAB, RAIDSTART, etc.

#should be commented out. If the references are in the comments, they

#can be ignored. References to MD devices, such as /dev/md0, should be

#replaced with the appropriate multipath device name.

#For example:

#RAIDTAB="/usr/local/cmcluster/conf/raidtab.sg"

#RAIDTAB=""

# MD (RAID) COMMANDS
