• Enhanced functionality in the ServeRAID Manager:
  • New Task Scheduler and Task Manager in the ServeRAID Manager Agent. Use this feature to schedule lengthy operations at a convenient time, such as a logical drive migration or synchronization.
  • Display options on the Preferences menu. Use this feature to choose sorting criteria for objects in the SeveRAID Manager tree and to choose the disk capacity unit of measure (megabytes or gigabytes).
  • Ability to set remote access ports in the ServeRAID Manager Agent configuration file (RaidAgnt.pps). This option no longer appears on the Preferences menu.

• Support for RAID Level-5EE logical drives on ServeRAID-6M, ServerRAID-4L, ServerRAID-4Lx, ServeRAID-4M, and ServeRAID-4Mx controllers.
• (For Windows NT and Windows 2000 only) The failover device driver can no longer be used for installation. You must install the regular Windows device driver first; then, update using the failover driver.
• Fixed a problem with OS/2, which caused data corruption on shut down. To fix the problem, the new OS/2 driver implements
  a two-pass shutdown procedure. The first pass issues a firmware flush cache command. The second pass waits eight seconds for the firmware to complete the flush; then, shut down resumes.
• Fixed a problem with the SCO OpenServer device driver, which sometimes caused a controller reset. This problem occured
  when the driver detected a bad command ID from ips bcopy.
• Fixed a problem during failover and server restart which caused clustered drives to be marked defunct.

• Fixed a cache flushing problem in the ServeRAID-3H/3HB controller. This problem could occur when: (1) the array includes a RAID level-5 logical drive running in WB mode; (2) a drive goes defunct during an active flush to that drive and then (3) an adapter is reset after another flush command is sent to the same sector on that drive. This fix was implemented in firmware to help increase data reliability.
• Fixed an intermittent system hang which can occur during a PCI bus scan when a ServeRAID 4M, 4L, 4Mx, or 4Lx is installed in slots 4, 5, and/or 6 of the x345 system.

• New audible alarm in ServeRAID Manager agent when critical and fatal events occur.
• The failover device driver for Windows operating systems is now an optional installation.
• Fixed a problem with the ServeRAID Manager “Send test trap” function. Certain management programs such as Tivoli Netview did not recognize the test trap.
• Fixed a problem with the ServeRAID Manager configuration wizard when creating large arrays near one terabyte or greater in size. The large arrays caused the ServeRAID Manager configuration wizard to display the wrong logical drive size.
• Fixed the following problem in the UnixWare/Open UNIX device driver: the device driver did not handle 64 bit DMA requests from the OS when greater than 4GB memory addressing was activated.
• (For Windows NT and Windows 2000 only, ServeRAID-3 family only): fixed “Event ID 11” condition in critical RAID-level 5 logical drives.
• (For Windows NT and Windows 2000 only): fixed “the service has terminated unexpectedly” error message reported in the event log.
• (For Windows NT and Windows 2000 only): fixed resource constraints under heavy workloads (Event ID 11).
• Reduced excessive error logging in critical RAID-level 1 logical drives.

For Microsoft Windows NT 4.0 only:

• Many causes of blue screens can lead to data corruption. In rare circumstances, if a blue screen occurs while a RAID level-5 configuration has one defunct physical drive, data corruption might occur. To reduce the risk of data corruption in this scenario, the ServeRAID Windows NT device driver now delays after a blue screen occurs before resetting the ServeRAID controller.
• Additionally, a fix was implemented for the rare occurrence of data corruption when all of the following conditions are met:
  • A ServeRAID-3HB controller is installed with the 4.70 or 4.80 firmware and device driver.
  • Four or more hard disk drives are in the array.
  • One or more of the hard disk drives in the array are 17GB or larger.
  • The array includes a RAID level-5 logical drive.
  • The server is turned off without shutting down the operating system, or a blue screen occurs.

For all operating systems:

• Fixed system hangs or error messages that might occur during tape backup operations or other single-threaded operations because of ServeRAID command time-outs. This problem was observed specifically on SCO OpenServer (“Unrecovered read error” messages are displayed on the OpenServer console).
• For IBM eServer xSeries 360: When using the “IBM ServeRAID 4.80 BIOS and Firmware Update (1 of 2)” diskette on a ServeRAID-4H controller, fixed occurrences when the firmware update did not complete successfully and the server would restart.
• The performance on some applications has been improved when using write-back mode on a RAID level-5 logical drive that has a defunct physical drive.

  • Caldera OpenLinux 3.1
  • Caldera Open UNIX 8.0

• Reporting of physical drive field replaceable unit (FRU) information within events. IBM service representatives use the FRU information to identify the physical drive model replacement without opening the server cover.

• Enhanced functionality in the ServeRAID Manager to establish a compatibility baseline, so that future releases will be able to connect and manage this release.
