Online Status Information

Software applications that run on HP-UX hosts display status and descriptive

information about the disk system and its components. SAM is the system

administrator’s interface to specific HP-UX functions. STM is the service

engineer’s tool for information, diagnostics, firmware updates, and more.

Viewing Component Status in SAM

SAM displays the status of disk system components on the host console. Follow

the instructions below to use SAM:

1 Select Disks and File Systems from the main window.

2 Select Disk Devices. SAM displays the hardware paths of all disks, disk

systems, and arrays on the host.

3 Select the path that represents the LCC of the desired disk system. You can

recognize the LCC by the description “HP Disk System 2405 Controller.”

4 Select View More Info from the Actions menu. A window displays header

information and a graphical representation of the front of the disk system.

The header provides the following information:

— LCC Hardware path - the path chosen from the Disk Devices list

— Peer LCC Hardware path - the path to the other LCC in the same unit

— Controller’s ID Switch Setting - Enclosure ID, set by the dial on the LCC

bulkhead

— Enclosure’s logical ID - the enclosure’s World Wide Name, a unique

identifier in the Fibre Channel network

5 For a view of the back of the selected disk system, click the “Back” tab.

6 To view component information, click the button representing the

component. SAM displays the following information about specific
