Last Update Date: 10/30/2006

Version 09.00.A5.22 - 10/30/2006

- Support for attaching the DS4000 EXP810 to the DS4300 Standard-

Dual Controller models or Turbo models and the DS4500-All Models.

- Fix C340532 106070 - Oracle Direct I/O error in Linux 2.4.21 kernel with

Linux RDAC version 9.00.A5.18. When the Oracle initial parameter for

filesystemio_options=directio (set to direct I/O), an error occurs

reading the control file and the Oracle instance just won't startup.

The cause of the problem is that starting with Linux Redhat3 (RH3)

2.4.21 kernel, a new vary_io feature was introduced. Each HBA lower

level driver must claim whether or not it support vary_io feature. The

Linux RDAC version 9.00.A5.18 did not do this resulting in error

reading the Oracle control files. This fix makes the Linux RDAC virtual

HBA driver synchronizes with physical HBA with respect to vary_io

feature support. The code is ifdefed for RH3 kernel version equal or

higher than 2.4.21.

Version 09.00.A5.18 - 07/28/2006

This is a re-released of the RDAC drive version 09.00.A5.18 to provide

support for

the attachment of DS4000 EXP420 Storage Expansion Enclosures.

- New 500G SATA Enhanced Disk Drive Modules (E-DDMs) in the DS4000

DS4700 storage subsystems and the EXP810 Storage Expansion Enclosures.

- New 500G SATA Enhanced Value Disk Drive Modules (EV-DDMs) in the

DS4000 DS4200 storage subsystem and the EXP420 Storage Expansion

Enclosures.

Version 09.00.A5.18 - 05/24/2006

- Support new DS4700 Storage Subsystem models 70A/H and 72A/H, which

support the attachment of DS4000 EXP710 and EXP810 Storage Expansion

Enclosures.

- Support new DS4800 Storage Subsystem Model 80A/H, which provides the

same functionality as the DS4500 Storage Subsystem, with better

performance.

- Support new 4Gbps Fibre Channel drives in the DS4000 EXP810 Storage

Expansion Enclosure.

Version 09.00.A5.09 - 6/30/2005

This is a re-release of the RDAC driver version 09.00.A5.09 to provide

support for the following items.

1. Red Hat 3 update 5 kernel for LoP servers environment.

2. The DS4800 storage subsystems with controller firmware

version 06.15.11.xx. With this version of firmware, the DS4800

controllers utilize all of the available data cache memory

installed in each controller blade for I/O caching. Previously

with controller firmware version 06.14.xx.xx, the DS4800

controllers used only the first 1G bytes of the installed data

cache memory per controller for I/O caching.
