parmodify2(1M)

For OA Based Partition Management Systems

parmodify2(1M)

determines whether the OA can automatically modify a parspec in order to enable a

partition operation (such as booting). In some scenarios, it is possible that the sys-

tem cannot meet the customer requested resource or attribute speciﬁcations in the

parspec for an nPartition or virtual partition. This can be due to non-existent

resources or degraded resources or other restrictions in hardware architecture.

Under these circumstances, the partition conﬁguration in the parspec may need to

be modiﬁed to make forward progress. The parspec change policy attribute of the

nPartition gives the customer the ability to choose the behavior in these cases. If the

parspec change policy is enabled (default), the affected partition operation is con-

tinued with available or modiﬁed resources or attributes after making the required

changes in the parspec. If the parspec change policy is disabled, the affected parti-

tion operation is failed and no changes are made to the parspec.

RETURN VALUE

The

parmodify command exits with one of the following values:

0 Successful completion.

1 Error condition occurred.

EXAMPLES

Add a new blade in enclosure 1 slot 3 to the existing nPartition 2 and activate it.

parmodify -p 2 -a blade:1/3:base:y:ri:50% -B

Add IO bay 2 in enclosure 6 to the existing nPartition 2.

parmodify -p 2 -a io:6/2:

delete a blade in enclosure 1 slot 3 from the existing nPartition 2.

parmodify -p 2 -d blade:1/3

Copy parspec of partition 1 to a new parspec called copy1_parspec

parmodify -p 1 -c copy1_parspec

Modify parpspec AltSpec to add a new blade in enclosure 1 slot 3.

parmodify -Z AltSpec -a blade:1/3:base:y:ri:50% -B

Modify Intended Active core value of partition 2 to 15.

parmodify -p 2 -n core:15

ERRORS

OA syslog contains additional description of errors encountered during partition operations. Users can

view the OA syslog from the OA using the SHOW SYSLOG OA command.

Error: System unable to accept partition commands

The above error message is printed out under the following circumstances:

• Attempting to run command from an OA other than the active OA in enclosure 1.

• System has been shut down (e.g. with POWEROFF XFABRIC, or ambient overtemp).

• The OA has not ﬁnished initializing.

In the above scenarios, please ensure the system and OA are completely up and you are running the com-

mand from the active OA in enclosure 1.
