Options

VOLUME(volser)

The volume serial number of a device that is online to the host attempting the snapshot.

UNIT({cuu|lowcuu-highcuu|lowcuu:highcuu|cuu(count)})

The unit address of one or more devices that are online to the host attempting the snapshot.

You can specify a single unit address or a range of unit addresses. A range can be specified as follows:

You can specify a range of unit addresses as follows:

• Specify the lowest address in the range and the highest address in the range separated by a hyphen or a colon: UNIT(lowcuu-highcuu) or UNIT(lowcuu:highcuu).
• Specify the starting address in the range and a count value (in parentheses) that indicates how many additional devices there are between that number and the highest address in the range: UNIT(cuu(count)).The count value includes the lowest and the highest units. For example, if you want to specify units 10 through 13, you would enter 4 as the count.

SYMDV#({symdv#|lowsymdv#-highsymdv#|lowsymdv#:highsymdv#|symdv#(count))})

Identifies the PowerMax or VMAX device number in the source storage system for the snapshot operation.

You can specify a single device number or a range of device numbers. A range can be specified as follows:

• Specify the lowest numbered device in the range and the highest numbered device in the range separated by a hyphen or a colon: SYMDV#(lowsymdv#-highsymdv#) or SYMDV#(lowsymdv#:highsymdv#).
• Specify the starting device number in the range and a count value (in parentheses) that indicates how many additional devices there are between that number and the highest numbered device in the range: SYMDV#(symdv#(count)). The count value includes the lowest and the highest numbered device. For example, if you want to specify devices 10 through 13, you would enter 4 as the count.

There is no limit on the number of devices specified as a range or a count value.

If you use SYMDV#, you must use it throughout the operation. That is, if you use SYMDV# for the source device, you must also use SYMDV# for the target device.

If you specify SYMDV#, the UNIT and VOLUME parameters are not allowed. However, you must use the LOCAL, REMOTE, or CONTROLLER parameters when you specify SYMDV#:

• LOCAL indicates that the device resides in a local storage system.
• REMOTE indicates that the device resides in a remote storage system accessible using the path that is specified with the RAGROUP subparameter.

SCFGroup(gnsgrp)

See SCFGroup. If you use SCFGroup, you must use it throughout the operation. That is, if you use SCFGroup for the source device, you must also use SCFGroup for the target device.
