Setting up a A3x00 in an independant controller configuration |
|
4 Jun 1999 |
Setting up a A3x00 in an independant controller configuration.
1) Install the Raid Manager software, along with the patches
on both systems.
2) Connect the A3x00 to one system to configure the luns to
go over the controllers you want them to.
3) Edit the /etc/osa/rmparams files on each system to disable
RDAC failover.
Change this line from FALSE to Rdac_SupportDisabled=TRUE
This line is towards the bottom of the file.
4) Run the following 'storutil' on the first system to let it
know you are going to run independant controller configuration.
storutil -c <raid module specifier> -i on
5) Shutdown the systems and hook up one cable from each system
to a controller port.
6) Run the same 'storutil' command on on the second system so
that will also run independant controller configuration.
7) Now the luns you configured on each controller will only be
seen from each the system connect to that controller.
NOTE: By configuring the A3x00 this way, you will no longer have the
redundancy of the controllers ability to failover luns. Please be
aware of this major limitation prior to setting this up.
