• SUSE Linux Enterprise Server 8 (Itanium) • SUSE Linux Enterprise Server 9 • SUSE Linux Enterprise Server 9 (AMD64/EM64T) • SUSE Linux Enterprise Server 9 (Itanium) • SUSE Linux Enterprise Server 10 • SUSE Linux Enterprise Server 10 (AMD64/EM64T) • SUSE Linux Enterprise Server 10 (Itanium) • Tru64 5.1B-3, 5.1B-4 Enhancements • Adds MSA1000 active/active support • Provides heterogeneous array support • Provides heterogeneous operating system access from Windows/Linux/HPUX hosts to single MSA1x00 • Supports persistent reservations - required by some multi-path and clustering applications • Provides enhanced rebuild and expand performance when priority is set to Medium or High • Increases default stripe size for RAID 5 and 6 (ADG) volumes from 16KB to 64KB. This results in performance improvement for most applications. • Adds support for the 750GB SATA hard drive installed in the MSA20 • Provides identification of system uptime on CLI output • Adds advanced SATA hard drive diagnostics Fixes • Cache management - Improves cache management to prevent I/O errors in the following situations: • During a LUN failover while the MSA controller is performing RAID migration or expansion under a heavy load • Preventing persistent host I/Os from bypassing cache when cache is dirty on powerup • Preventing I/O timeouts in cases where many implicit failover events occur within a short period of time • Default profile - With version 7.00 of the firmware, the default profile loads the correct host mode settings after upgrading from an earlier release of firmware. This was not the case when upgrading to version 6.86 from an earlier version; in this situation, the default profile might not have loaded the correct host mode settings when assigned to a host connection. Any host connection that was left set to "Default" and not set to the correct host mode profile, such as Windows or Linux, would fail to load support software, such as the ACU, event notification driver, or multi-path software. Prerequisites MSA20 version 2.02 or later Installation instructions For instructions on installing the firmware, see the MSA1000 or MSA1500 installation guide and the HP StorageWorks 1000/1500 Modular Smart Array firmware updating guide located on the Technical Documents page of the following websites: http://www.hp.com/go/msa1000 or http://www.hp.com/go/msa1500cs.
