parspec(5)

For OA Based Partition Management Systems

parspec(5)

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 contin-

ued with available or modiﬁed resources or attributes after making the required changes in the parspec.

If the parspec change policy is disabled, the affected partition operation is failed and no changes are

made to the parspec.

For example, consider the scenario where the memory granularity speciﬁed by the user cannot be accom-

modated by the system and a new memory granularity value has to be applied. This is likely to affect the

virtual partition memory sizes speciﬁed by the user and stored in the parspec since they will have to be

rounded up to be a multiple of the new memory granularity. Users may want to make virtual partition

memory size adjustments manually and not have the system make any changes in the virtual partition

memory sizes they have assigned. In that case, they would have to disable the parspec change policy for

the nPartition before they conﬁgure and boot virtual partitions.

Additional examples of resources that would require modiﬁcation to allow a partition to boot are: non-

existent root ports, deconﬁgured root ports, oversubscription of CPUs, or non-existent socket for socket-

local CPUs or socket-local memory assignment to virtual partitions. Note that nPartition resources may

be assigned to an nPartition without being activated. Since assignment and activation of nPartition

resources can be performed independently, they need not be removed from a parspec in the event of a

deconﬁguration, and will not prevent the nPartition from booting.

EXAMPLES

Create an alternate

parspec myPs1 containing the blade in enclosure 1 slot 1.

parcreate -C myPs1 -a blade:1/1:base:y:ri:75%

Create an nPartition with a current parspec named

myParspec2, containing the blade in enclosure 1

slot 2.

parcreate -C:y myParspec2 -a blade:1/2:base:y:ri:25%

Create a two blade nPartition nextPartition

from a saved parspec nextPartition_copy.

parcreate -Z nextPartition_copy

Modify alternate parspec AppSpec to add a new blade in enclosure 1 slot 3 to the nPartition deﬁnition.

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

Create a new alternate parspec from the current, active nPartition 1 (save the conﬁguration).

parmodify -p 1 -c newPartition

Remove inactive nPartition 2 and it’s associated current

parspec.

parremove -p 2 -Z

Remove an alternate parspec myParspec.

parremove -Z myParspec

Display the list of current parspecs.

parstatus -z -P

Display the list of all parspecs, both current and alternate.

parstatus -z

Display the nPartition conﬁguration information maintained in the default parspec for nPartition 1,

ps0001. Note that this command can be performed on either a current or alternate parspec.

parstatus -Z ps0001

Display the virtual partition conﬁguration information for all deﬁned virtual partitions maintained in the

default

parspec for nPartition 3, ps0003. Note that this command can be performed on either a

current or alternate parspec.

vparstatus -Z ps0003

Save the current conﬁguration of nPartition 1, and switch to an alternate conﬁguration.

parmodify -p 1 -c Saved_Config

poweroff partition 1

parremove -p 1
