=head1 DESCRIPTION
|
|
|
|
=head2 PPC specific:
|
|
|
|
The chvm command modifies the partition profile for the partitions specified in noderange. A partitions current profile can be read using lsvm, modified, and piped into the chvm command, or changed with the -p flag.
|
|
|
|
This command also supports to change specific partition attributes by specifying one or more "attribute equals value" pairs in command line directly, without whole partition profile.
|
|
|
|
=head2 VMware specific:
|
|
|
|
The chvm command modifes the vm specified in noderange. Calling with deregister or purge options at the same time as the resize option is not recommended.

B<--cpus count> Set the number of CPUs.
|
|
|
|
B<-d disk> Deregister the Hard disk but leave the backing files. Multiple can be done with comma separated values. The disks are specified by SCSI id. Size defaults to GB.
|

|
|
|
|
B<-p disk> Purge the Hard disk. Deregisters and deletes the files. Multiple can be done with comma separated values. The disks are specified by SCSI id. Size defaults to GB.
|
|
|
|
B<--resize disk=size> Change the size of the Hard disk. The disk can never be set to less than it's current size. Multiple disks can be resized to I<size> by using comma separated values on the left side of B<=>. The disks are specified by SCSI id. Size defaults to GB.

|
|
|
=head2 PPC specific:
|
|
|
|
1. To change the partition profile for lpar4 using the configuration data in the file /tmp/lparfile, enter:
|
|
|
|
I<cat /tmp/lparfile | chvm lpar4>
|
|
|
|
Output is similar to:
|
|
|
|
lpar4: Success
|
|
|
|
2. To change the partition profile for lpar4 to the existing profile 'prof1', enter:
|
|
|
|
I<chvm lpar4 -p prof1>
|
|
|
|
Output is similar to:
|
|
|
|
lpar4: Success
|
|
|
|
3. To change partition attributes for lpar4 by specifying attribute value pairs in command line, enter:
|
|
|
|
I<chvm lpar4 max_mem=4096>
|
|
|
|
Output is similar to:
|
|
|
|
lpar4: Success
|
|
|
|
=head2 VMware specific:
|
|
|
|
I<chvm vm1 -a 8,16 --mem 512 --cpus 2>
