Before installing your SAN Volume Controller,
you need to complete certain steps with your disk controller
systems and switches.
Perform the following steps before installing and configuring
your SAN Volume Controllers:
- Install and configure your disk controllers.
Attention: To prevent loss of data, virtualize only those redundant
array of independent disks (RAIDs) which provide some form of redundancy,
that is, RAID 1, RAID 10, RAID 0+1 or RAID 5. Do not use RAID 0 because
a single physical disk failure might cause the failure of many virtual
disks.
- Create the RAID resources that you intend to virtualize.
- Install and configure your switches to create the two zones
that the SAN Volume Controller needs:
- A disk zone that contains all the RAID controllers and
the SAN Volume Controller.
- A host zone that contains all your host adapters and
the SAN Volume Controller.
