Disk Attribute Descriptions

This list describes all the attributes that can be used to define magnetic disks, virtual

disks, and disk profiles. Attributes that are not valid for certain commands, the

PROFILE object, or virtual disks are indicated accordingly.

ALTNAME $vol

is an alternate volume name for the disk.

This attribute changes the alternate volume name on the label of the disk but does

not change the system configuration database.

If the storage subsystem tries to start a volume and the default volume name is

already in use, the volume is started using the alternate volume name. If the

alternate volume name is also in use, the storage subsystem uses the volume

name in the system configuration database and the disk is left in the DOWN state.

To use this attribute, see Naming a Magnetic Disk on page 6-26.

ANTCAPACITY number

is the maximum number of entries in the virtual-disk, audited-name table.

number is in the range 0 through 2500000. The default is 12288.

The value of this attribute must be large enough to hold not only the temporary and

permanent files to be created on the virtual disk but also the normal overhead

associated with key-sequenced files, as documented in the Enscribe

Programmer’s Guide.

ANTLOCATION { $vol | $vol.subvol.fileid }

is the magnetic disk location of the audited-name table for the virtual disk.

This attribute is required for the ADD command and has no default (not even when

you use the LIKE attribute).

If you use the $vol.subvol.fileid format, fileid must exist and must

reside in a subvolume whose name begins with ZYS.

If you use the $vol format, $vol must be in the STARTED state, enabled in

TMF, and configured to be in a storage pool. The virtual disk determines the

subvolume name and file ID for the audited-name table it creates.

Note. This attribute is not valid for the ADD DISK command and the PROFILE object.

Note. This attribute is only valid for virtual disks.

Note. This attribute is only valid for virtual disks and cannot be used with the ALTER DISK

command.
