3.11 Power on the Disk Enclosure <= CUSTOMER TASK
STEP 53
If you are running AIX, remove the appropriate mpt2sas devices (those attached to the DE) from the Operating
Systems owning the DE now before the DE is turned back on so that there is not time wasted in spinning down the
drives.
If you are running Linux, no action is necessary.
STEP 54
Power On the Disk Enclosure from the BPC FSP command line by using the following command:
This is the command syntax:
bpccmd –c 41<blank>0000<Cage ID>
<blank>
= “11”
<Cage ID>
= see Figure 6
Type in the following, inserting the correct Cage ID for the damaged DE chassis location:
bpccmd –c 41110000xx
Where “xx” is the Cage ID of the DE you are replacing.
This field will be 05,07,09,0B,0D, or 0F (see Figure 6).
The correct return code is 001100. If you do not receive this, contact the next level of support.
ATTENTION:
Be very careful that you are in the correct frame and that you type this command exactly as it will
power on the cage you type. If you are off by just one digit, you can easily power on a CEC or DE in another cage
of the frame.
