HP-UX 11i December 2004 Release Notes

General System Administration and Performance Monitoring
Changes to System Administration Manager (SAM)
Chapter 9
214
Peripheral Devices
updated for
March 2003
• The HP-UX iSCSI (SCSI over TCP/IP) Software Driver is now supported by SAM.
With SAM, system administrators can add/remove iSCSI drivers from the kernel
and can manage storage accessible by the iSCSI Software Driver. SAM provides
system administrators with a user interface to view statically configured iSCSI
targets, add new iSCSI targets, and delete existing iSCSI targets from the kernel
registry. This functionality is available from SAM -> Peripheral Devices -> iSCSI
subarea.
updated for
June 2001
• Added support for PCI Card Online Addition and Replacement (OLAR) on systems
with OLAR-capable hardware, for Superdome systems, N-Class, and L-Class
systems.
This change allows you to add or replace PCI cards online without requiring a
reboot. SAM shows the I/O slot number and the OLAR driver state (active,
suspended, error, not OLAR-capable). Through the Actions menu in the
Peripheral Devices / Cards screen, you can replace a card, turn on the I/O slot
attention LED (so you can locate the slot more easily), bring a suspended card online,
and view OLAR-specific information about the card and slot. In addition, different
instructions are provided depending on whether or not the card is in a slot that is
capable of OLAR.
NOTE SAM patch PHCO_23004 for 11i (included in the HWEnable11i patch bundle and
automatically installed) changes the behavior of the PCI card slot LED (Attention
Indicator) to conform with the newly implemented PCI SHPC (Standard Hotplug
Controller) specification.
Essentially, the meanings for OLAR “FLASHING” (BLINKING) and “ON” LED are
reversed to meet the specification.
See “New Attention Indicator Behavior” on page 77 in Chapter 4 for more details.
• Modified cards screen layout to be hierarchical.
You can open mass storage interface cards (SCSI, fibrechannel) to view storage
devices attached to a card. This enables you to quickly identify devices controlled
through a particular card resource and therefore affected if the card were suspended.
Because only the attached devices are displayed, the hierarchical view is more
convenient and easier to use then backtracking to the Devices List from the
Peripheral Devices area.
• Added new Actions menu item, Analyze Critical Resources.
This menu item displays a dialog listing all resources, including devices, file systems,
device files, and processes that are affected if the selected card fails or is suspended
from operation. It will work on systems and cards that are capable of OLAR, as well
as those that are not. It determines if any of the resources are critical to HP-UX or
SAM (and this would cause either to fail if the resources were lost). This menu item
properly accounts for resources that have alternates, backups, or mirrors.
• Added support for DLT device tape densities (DLT_42500_24, DLT_42500_56,
DLT_62500_64, DLT_81633_64).
