1 SerialSCSI-00 (sasd) overview The SerialSCSI-00 bundle contains the sasd driver for the AH303A PCIe SC44Ge SAS Host Bus Adapter, and the core-only HP 8 Internal Port SAS Controller and HP Multi Port Internal SAS Controller. The sasd driver is always installed. 2 New and changed features in this release 2.1 New features There are no new features included in SerialSCSI-00 at the time of this publication. 2.
.1 HP 8 Internal Port SAS Controller and HP Multi-Port Internal SAS Controller • Updating the adapter firmware to version 1.23.33 or later might change the target ID of disk devices. This occurs on HP Integrity rx2660, rx3600, and rx6600 servers when an Integrated RAID volume is configured on the controller and you perform one of the following actions: ◦ Update the adapter firmware offline using sasflash.efi.
4.3 All controllers supported by SerialSCSI-00 • Unnecessary reboot occurs when removing the sasd driver. If you use swremove to remove the dynamically loaded sasd driver, the Critical Resource Analysis (CRA) can fail. This causes the swremove command to incorrectly reboot the system. Severity: Low Corrective Action: To avoid this CRA failure, before running swremove install patch PHCO_36356 (or a superseding patch). Patches are available from the HP IT Resource Center at: http://itrc.hp.
5 Recommendations This section provides recommendations for highest performance and reliability. • Updating Physical Disk Firmware Consider the following when you use sasmgr(1M) to update the firmware of physical disks that are part of a RAID volume attached to an HP 8 Internal Port SAS Controller: ◦ If you are updating the firmware on two or more disks that are part of a RAID volume, do not issue multiple commands to download simultaneously.
