The NEWSET command creates a new volume set by initializing the master of the volume set. Nonsystem volumes have only permanent space and should be set to 100 for percentperm. The volume master must be mounted in the SCRATCH or UNKNOWN state in order for the NEWSET command to initialize a new volume set. Task | |
Creates a new volume set. Capability | |

Parameters | |
- sname
The name assigned to the new volume set. It is used to reference and identify the set, so it must be unique to the system. Required. - master
The name assigned to the master volume of the set. The name assigned to the master volume need not be the same as the name of the volume set. Required. - ldev
A number from 1 to 100 specifying the logical device on which the
master volume being created is mounted. It must specify a drive with
a volume in the SCRATCH or UNKNOWN state. Required.
- percentperm
A number between 0 and 100 specifying the maximum percentage of disk space that can be allocated as permanent. Optional. - percenttrans
For system volumes only, a number between 0 and 100 specifying the maximum percentage of disk space that can be allocated as transient. Optional. - gen_number
A number from 0 to 32767 specifying the generation of the new volume. The default is 0. Optional. - cname
The names of the volume classes to be initially created in the volume set. The master volume (volume being initialized) is assigned to these classes. If this parameter is omitted, the volume class DISC is created, and the master volume is assigned to it. Optional.
Example | |
This example shows how to create a new volume set from a volume in either the UNKNOWN or SCRATCH state. Use the DSTAT command to check the states of the volumes in the volume set. Use the NEWSET command to create a new volume set, BSET. Use the DSTAT command to verify that the new set was created.
volutil: :DSTAT

23-079350 SCRATCH
volutil: NEWSET SNAME=BSET MASTER=BVOL1 LDEV=21 PERM=100
*Verify: Initialize new volume set BSET:BVOL1 on ldev 21 [Y/N]? Y
*Note: New master volume has been initialized on ldev 21.
