Compaq 112726-001 - ProLiant - 6500 Integration Notes page 16

To perform a simple verification of operation, press F on the keyboard. Compaq recommends
that you pause the NHAS software during these tests, by typing P, so an automatic failback
cannot take place. Pressing F will force a server to fail. The failed server should report the
status as FAILOVER. Soon after the induced failure, both servers should recognize that they
are both operational. The surviving server will return to COSTANDBY state when the
previously failed server enters the RECOVERY state. If successful, both servers in the NHAS
cluster will fallback to COSTANDBY state and all quorum arbitration links will be
connected.
Some other commands to note:
C - Changes the first server into the COSTANDBY state.
ESC - Used to exit the program. When the Escape button is pressed, you are presented with a
confirmation prompt. Choose Yes to exit, or choose No to remain in the application.
F - Initiates a manual failover on the first server. When you press f, you are prompted to
confirm that you want to manually failover the first server and acquire the disk devices from
the second server.
H - Displays the Help screen.
P - Pauses the AutoSwitch feature. When you press P, the AutoSwitch feature is paused and
automatic failover or rollback will not take place. When you pause NHAS, the status turns
red to indicate that the server cannot change states. To unpause the NHAS Console, press p
again. Note that the Pause feature does not affect a transitional state. For example, once the
failover process has reached the ENTERING FAILOVER state, the Pause feature will not
stop the failover.
R - Changes the server into the RECOVERY state without changing the second server to the
FAILOVER state. Any shared volumes are dismounted and any shared drives are released. If
you want to failover the system, press F on the second server, which will force first server
into the RECOVERY state.
If the failover was unsuccessful, check the network configuration and verify that it is properly
set up.
If further problems persist, check the AUTOEXEC.NCF file for the following entries:
REM HA Server Installation
Search Add Sys:\HASERVER
Set Auto Restart After Abend=0
Load VincaCom
Load VincIPX (master/slave)=address, card SLUNBIND
Load HASERVER
LOAD HASTRUST
If any of these entries are incorrect, you should either edit the file to reflect the correct
information or reinstall NHAS.
If problems continue, check SYS:\HASERVER\HASERVER.LOG for errors. Contact your
local support representative if necessary.
