Subsystem Device Driver for AIX

The Subsystem Device Driver is a pseudo device driver designed to support the multipath configuration environments in the IBM TotalStorage Enterprise Storage Server, the IBM TotalStorage DS family, and the IBM System Storage SAN Volume Controller. It resides in a host system with the native disk device driver and provides the following functions:

- Enhanced data availability
- Dynamic I/O load-balancing across multiple paths
- Automatic path failover protection
- Concurrent download of licensed internal code
- Path-selection policies for the host system

The AIX SDD installation package can run in single host system environment, or multiple hosts High-Availability Cluster Multiprocessing (HACMP) environment, supporting both HACMP concurrent mode, and non-concurrent mode.

Please see the Multipath Subsystem Device Driver User's Guide for any additional prerequisite information.

See the "Multipath Subsystem Device Driver User's Guide" for installation and usage information.

See the "Readme" file below for information regarding defects and fixes that are associated with this level of SDD code.

See the "SDD Flash Documents" for any post-release, critical product information.

Refer to the "Support Matrix for Subsystem Device Driver (SDD), Subsystem Device Driver Path Control Module (SDDPCM), and Subsystem Device Driver Device Specific Module (SDDDSM)" and the corresponding storage interoperability matrix to determine the support level for your configuration.

Warning: SDD 1.6.2.0 or later for 52 and 53 OS requires AIX52 TL08 and AIX53 TL04.
