The node rescue codes are displayed on the menu screen during node rescue.
Start node rescue if the boot image on the hard disk is missing or corrupted. Corrupted code is indicated during the boot process either by the display of an error code or by a hang condition.
To
start node rescue, press and hold the left and right buttons
on the front panel during a power-on cycle. The menu screen displays
the Node rescue request. See the node rescue request topic. The hard
disk is formatted and, if the format completes without error, the
software image is downloaded from any available node. During node
recovery, Line 1 of the menu screen displays the message Booting followed
by one of the node rescue codes. Line 2 of the menu screen displays
a boot progress indicator. Figure 1 shows
an example of a displayed node rescue code.
The three-digit code that is shown in Figure 1 represents a node rescue code.
Attention: If the 2145 UPS is
only connected to this SAN Volume Controller,
the 2145 UPS turns
off within five minutes of a node-rescue process failure. For example,
if a donor node cannot be found. When the problem that is preventing
node rescue has been resolved, the 2145 UPS must
be turned on before turning on the SAN Volume Controller.
Note: The 2145 UPS-1U will
not power off following a node rescue failure.
