vparmodify2(1M)

For OA Based Partition Management Systems

vparmodify2(1M)

NOTE: When using socket local syntax (socket

:socket_id:cpu::num), only the number of cores on

the given socket may be entered, not the hardware paths of the individual cores.

• io_path for:

1) Blade resident I/O is speciﬁed as enclosure#

/blade#/IO_hub#/root_complex#

/root_port#

For example:

Short form: 3/6/0/1/2

Medium form: iorp-3/6/0/1/2

Long form: enclosure3/blade6/iohub0/iorc1/iorp2

2) I/O bay resident I/O is speciﬁed as enclosure#

/IO_bay#/IO_hub#/root_complex#

/root_port#

For example:

Short form: 7/1/0/1/2

Medium form: iorp-7/1/0/1/2

Long form: enclosure7/iobay1/iohub0/iorc1/iorp2

• ioslot_path for:

1) Blade resident I/O is speciﬁed as enclosure#

/blade# /io_slot#

For example:

Short form: 3/6/1

Medium form: ioslot-3/6/1

Long form: enclosure3/blade6/ioslot1

2) I/O bay resident I/O is speciﬁed as enclosure#

/iobay# /

io_slot#

For example:

Short form: 7/1/4

Medium form: ioslot-7/1/4

Long form: enclosure7/iobay1/ioslot4

Note that there is a one-to-one correspondence between root ports (speciﬁed along with io_path) and

ioslots (speciﬁed along with ioslot_path) on SD2 servers. The verbose output of blades and iobays

displayed by parstatus shows the correspondence between rootports and ioslots.

• Please note that unlike nPartitions, vPartition ilm_size and size are speciﬁed in MB (megabytes).

The commands round ilm_size and size upward as required to the granule increment in effect for that

memory type. ilm_size and size may be speciﬁed in decimal or in hexadecimal. A hex speciﬁcation

should be preceded by 0x, as in 0x8000000.

• Note that cpu related modiﬁcations may be effected on a vPar even in UP state. For any other

resource modiﬁcations (such as ioslot or memory), the vPar must be in DOWN state.

SECURITY RESTRICTIONS

When invoked from the OS, this command is restricted to processes owned by superuser having appropri-

ate

parperm privilege. An OA user with operator privilege level or above can modify virtual partitions

from the OA.

RETURN VALUE

The

vparmodify command exits with one of the following values:

0 Successful completion.

1 One or more error conditions occurred.

EXAMPLE

Change the name of the virtual partition called

Oslo to Bergen:

vparmodify -p Oslo -P Bergen

Add two processors to the virtual partition Oslo (cpu and core syntax):

vparmodify -p Oslo -a cpu::2

vparmodify -p Oslo -a core::2

Add two socket-local processors from enclosure 3, blade 6, socket 0 to the virtual partition Oslo (cpu and

core syntax):
