2003 (32-bit) Installation and Configuration Guide
Note: For the previous two storageset configurations, this is a combined maximum,
limited to no more than 20 RAID 3/5 storagesets in the individual combination.
■ 8 partitions of a storageset or individual disk
■ 6 physical devices per RAID 1 storageset (mirrorset)
■ 14 physical devices per RAID 3/5 storageset (RAIDset)
■ 24 physical devices per RAID 0 storageset (stripeset)
■ 48 physical devices per RAID 0+1 storageset (striped mirrorset)
■ 146 GB disks—the largest supported by the HSG60 and HSG80 storage array.
Tip: If you are redeploying disks that have been operating under a prior version of
ACS into a newly established container, as a best practice,
always initialize the devices
and the new container before proceeding with subsystem activities to avoid operational
and performance issues.
Note: HSG60 and HSG80 array controllers do not support greater than 146 GB. This
restriction is enforced by the firmware.
Addressing Conventions for Device PTL
The HSG80 controller has six SCSI device ports, each of which connects to a
SCSI bus. In dual-controller subsystems, these device buses are shared between
the two controllers. (The StorageWorks Command Console calls the device ports
“channels.”) The standard BA370 enclosure provides a maximum of four SCSI
target identifications (ID) for each device port. If more target IDs are needed,
expansion enclosures can be added to the subsystem. For an example of how units
are mapped to physical disk drives, see Figure 20.
