3.5 Running the SWCC Failover Transition Module Installation Script

The SWCC Failover Transition Module Installation Script automates the final

software configuration tasks required to establish failover of the StorageWorks

Command Console agent, which are:

•

Install the (HP) SCSI pass through device drivers on all the remaining

clustered servers. (These drivers should already reside on your

primary

host,

via the SWCC agent installation process performed in Section 3.2).

WARNING

Installing the SCSI pass through drivers requires a

reboot of all servers on which it will be installed.

•

Install the SWCC Failover Transition Module (agent) in an MC/ServiceGuard

“package” on all clustered servers.

In order for the SWCC RAID Manager agent to failover in the case of a server

shutdown, it must be installed in a “package” in the MC/ServiceGuard software

that resides on each host server. A copy of the package resides on all hosts.

Under normal operating conditions, the RAID Manager will run on the primary

host only. When the primary host is unavailable as in a failover,

MC/ServiceGuard will start up the RAID Manager on a secondary, assigned

takeover host.

To obtain and invoke the SWCC Failover Transition Module Installation Script

required for your MC/ServiceGuard cluster configuration, proceed as follows:

1. Download a copy of the tar file (ha_stm_hp01.tar) into your

/tmp

directory,

from the following StorageWorks website address:

http://www.storage.digital.com/menusupport.htm

2. Set your current directory to

/tmp

3. Extract the script software from the downloaded files by issuing this

command:

tar xvf /tmp/ha_stm_hp01.tar
