3.5.1 Preparing an Existing RAID Array for Secure Path Operation
If you have an existing RAID Array that is currently being used in a production
environment and plan to reconfigure for Secure Path operation, you should perform the
following steps before proceeding to Chapter 4:
1. Follow normal procedures to backup the data stored on all drives configured on the
RAID Array.
2. Check that your RAID Array subsystem does not make use of controller-based
partitioning. Partitioned storagesets and partitioned single-disk units are not
supported in Multiple-Bus failover, dual-redundant configurations. Re-configure to
eliminate any controller-based partitions.
WARNING
Before you delete any partitions on the RAID Array, backup
your data and then use Windows NT Disk Administrator to
delete the partition(s) from the drives before you delete the
storage unit(s) from the RAID Array configuration.
3.5.2 Preparing a New RAID Array for Secure Path Operation
If you have a new RAID Array that will be configured for Secure Path operation, you
should perform the following steps before proceeding to Chapter 4:
1. Install the RAID Array in a single path configuration according to the installation
documentation you received with the platform kit.
2. Use StorageWorks Command Console (SWCC) or CLI to establish the desired
storageset configuration. Do not use controller-based partitions in your RAID Array
configuration.
3. Use Windows NT Disk Administrator to partition and format the storagesets.
