CAUTION: This procedure results in loss of data. This procedure must be used only if the HMC
operating system is either not installed, incorrectly installed, or corrupted.
To create the RAID1 logical drive and to rebuild the content on that drive, run the following commands
from the Petitboot shell:
1. Create the RAID1 logical drive:
/bin/arcconf create 1 logicaldrive name “HMC Disk” max 1 0,0 0,1
2. Display the logical drive to confirm that is was created:
/bin/arcconf getconfig 1 ld
3. Enable the automatic rebuild of the logical drive:
/bin/arcconf setcontrollerparam 1 spareactivationmode 1
If you need to remove the RAID1 logical drive:
/bin/arcconf delete 1 logicaldrive 0
Sensor status
You can check the sensor status to quickly determine the general health of the system without using the
event codes.
To view the sensor status, use the following command:
openbmctool -U <username> -P <password> -H <BMC IP address or BMC host name> fru status
To view the sensor status and any corresponding event codes, use the following command:
openbmctool -U <username> -P <password> -H <BMC IP address or BMC host name> fru status -v
Sensors that have a status of present and functional do not require a service action. Sensors that have a
status of present and not functional require a service action.
Some occurrences of errors in the system might not appear in the sensor status. After you view the sensor
status, look for event codes to determine whether a service action is required.

Learn how to disconnect and connect the power cords on IBM Power Systems HMC (7063-CR2) systems.
Disconnecting the power cords from a 7063-CR2 system
To disconnect the power cords from an IBM Power Systems HMC (7063-CR2) system, complete the steps
in this procedure.
Before you begin
Note: This system might be equipped with two or more power supplies. If the removing and replacing
procedures require the power to be off, then ensure that all power sources to the system are
disconnected.
Procedure
1. Identify the system unit that you are servicing in the rack.
For instructions, see “Identifying the 7063-CR2 system that contains the part to replace” on page 96.
2. Unfasten the hook-and-loop fasteners from the power cords.
