Path and Drive Status Monitor
The two paths (Path 0 and Path 1) are displayed in green by the SecurePath Manager
when both paths (host bus adapters, cabling, and controllers) are functioning
normally. The Manager keeps track of the primary path (bus assignment) for each
disk in the storage subsystem. When operating normally, the Manager displays each
disk on the primary path to which it has been assigned as a disk icon, shaded yellow
and gray. If a drive letter has been assigned to the disk, it will be displayed above the
disk icon.
Determining Disk Identity
Drives configured in a multipath environment may be identified in three ways. If you
move the cursor over a disk icon, Secure Path Manager will display the various
identities of a drive/port/bus/target/LUN and disk number. You may also view this
information by right-clicking the mouse on the disk icon to launch the properties
dialog for the drive.
The port/bus/target/LUN information refers to the physical identity of the drive’s
corresponding storageset (unit) as designated by the storage subsystem. The disk
number refers to the number assigned to a drive by the Windows Disk Administrator,
and the drive letter appearing above the drive icon is assigned to that partition (if one
exists) by the system administrator. If a drive has more than one partition, the disk
number also appears above the drive. This drive information should allow you to
quickly map the storageset to operating system identity and determine which
storagesets are currently serviced through each path.
Assigning New Primary Paths to Drives
To assign a new primary path to a drive:
1. Use the left mouse key to select the icon of the disk that is to receive a new
primary path assignment (the icon becomes a null-circle when selected).
2. Drag the disk icon from its current primary path to the alternate path displayed on
the screen (the icon turns gray while in transition, and the cursor changes to a
squared arrow).
