For more information on using MTCCONS, see the AA 4000 Users
Guide.
Removing Components
Most components of the HPAA system can be removed from
participating in the array.
The advantage of being able to take this
step is to proactively remove a component for maintenance that will
prevent the AA 4000 software from reporting the same errors again
and again, or worse, “failing” the component out of the system.
A
component that has been “failed out” must be manually enabled
upon repair.
For the purposes of administering the HPAA system,
the terms “remove” and “disable” are synonomous.
Disabling (Removing) a CE
This command disables (removes) the specified CE from the active
AA 4000 configuration. For the CE to rejoin the array use the CE
Enable Operation command.
WARNING
If only one CE is in operation, use a Windows NT
Shutdown whenever possible. This command does not
perform a normal Windows NT shutdown.
As a result, any
data in the NT disk cache that has not been written to disk
can be lost.
Using MTCCONS
MTCCONS CEn Disable Operation From IOPx -
disable_safeguard
Using Display and Control
Double-click on the picture of the CE to be disabled and from the
Control and Display window choose the disable command.
Once the operation is performed, the CE resets, goes through POST,
and reboots. The CE reinitializes, but cannot boot or synchronize
with the AA 4000 array until a CE Enable Operation command is
issued.
To verify that the CE is disabled, on either IOP or the
remaining CE check the status in the Marathon Manager Main or
issue an IOPn Show Configuration command.
Disabling (Removing) an IOP
This command disables (removes) the specified IOP from the active
AA 4000 array. Use this command to start a maintenance procedure
or to remove an IOP that is not operating properly (this will allow a
verification to take place to see if the system operates correctly
