Creates and enables a quota file for a disk volume that does not currently contain one. Requires write (W) access to the volume's master file directory (MFD), plus one of the following items: SYSPRV privilege, a system UIC, or ownership of the volume. Format DISKQUOTA CREATE
1 – Qualifier
1.1 /DEVICE
/DEVICE=device-spec Specifies the disk volume on which to create a quota file. SYSMAN validates the device specification. A logical name may be specified for device-spec. If so, it is translated in the target environment. Without a device specification, SYSMAN uses the default disk on the target node. Unless you have set a default device with the SET PROFILE command, the default disk is the current device on the local node or the login default device on another node, depending on the established environment.
2 – Description
The DISKQUOTA CREATE command creates a quota file for a volume that does not currently have one. Only one quota file, [000000]QUOTA.SYS, can be present on any volume or volume set. As soon as you create a quota file, establish default values for quotas and overdrafts by adjusting UIC [0,0] with the DISKQUOTA MODIFY command. When a disk has existing files, use the DISKQUOTA REBUILD command to have SYSMAN update the quota file to contain current usage values. NOTE VSI recommends that you do not create and enable a quota file on the system disk unless users are allowed to create files on that disk.
3 – Example
SYSMAN> SHOW ENVIRONMENT %SYSMAN-I-ENV, Current command environment: Node NODE24 of local cluster Username ALEXIS will be used on nonlocal nodes SYSMAN> DO SHOW DEVICES . . . SYSMAN> DISKQUOTA CREATE /DEVICE=DJA31: SYSMAN> DISKQUOTA MODIFY /DEVICE=DJA31: [0,0] - _SYSMAN> /PERMQUOTA=10000 /OVERDRAFT=100 The commands in this example sequence display the characteristics of the current management environment and verify the device name. Then they create a quota file on the disk DJA31 and set up default quota values.
