AH303A PCIe SC44Ge SAS Host Bus Adapter for Integrity Servers Support Guide, September 2009

disable
Disables the controller. This is a destructive operation. The controller goes
offline, all current I/Os are aborted, and new I/Os fail. You must perform an
enable operation to bring the controller back online. If the -f option is not
specified, sasmgr displays a warning message before continuing the command.
Otherwise, it suppresses the warning message and executes the command.
download
Updates the firmware on a SAS controller, enclosure, or SAS disk. You can
specify the following qualifiers:
• downloadfile – The name of the file containing the new firmware.
• enc_bay – The enclosure and bay of the disk to update the firmware on.
OR
ctrl – The ID of the external enclosure to update the firmware on.
OR
device_file – The device file of the SAS controller to update. This
qualifier also requires the use of the hba qualifier. For more information
on the use of this command, see “Updating SAS Controller Firmware
Online” (page 57).
NOTE: To update SAS controller firmware online, you must be running
version 11.31.0909 or higher of the sasd driver. Online SAS controller firmware
updates are not supported on systems running HP-UX 11i v2.
If you do not specify the -f option with this command, sasmgr displays a
warning message before continuing. Otherwise, it suppresses the warning
message and executes the command.
enable
Enables the controller and brings it back online. This command causes the
driver to initialize the controller. Use this command to bring the controller
back online after using the disable command.
get_info
When run without qualifiers, it returns information about the controller
represented by device_file. You can specify the following qualifiers:
• lun – Shows hardware path and SAS address information for a specific
LUN or all LUNs. If you specify the -N option and the -q lun=all
qualifier, it displays persistent device file information.
• lun_locate – Shows LUN location information for the LUN specified
with the LUN qualifier. If you specify the -N option and the -q lun=all
qualifier, it displays persistent device file information with the LUN
location information.
• pci_id – Shows PCI ID information for the controller.
• phy – Shows information about all PHYs or a specific PHY.
• phy_in_port - Shows information about a port that the specified PHY
belongs to or provides information about all ports.
• reg - Displays the contents of a specific PCI config space or MMIO register
or all PCI config spaces or MMIO registers. You specify the PCI config
space or MMIO register type with the reg_type qualifier. If you do not
specify the reg_type, the command assumes a default register type of
MMIO.
• smp_addr – Shows the SMP initiator SAS address to send SMP requests.
• target – Shows information about a specific target or all targets.
• vpd – Shows vital product data for the controller.
