Chapter 18 BACKUP+ Commands
READALL
Option: DRIVES
Allows the parallel use of multiple backup devices for READALL. The serial handling of multiple backup devices
is not permitted with the READALL command.
Tape drives must be of the same type (e.g., tape or DDS but not mixed) and density and configured with the
same device class.
Syntax
>READALL ...;DRIVES=numdrives
numdrives
The number of backup devices, between 1 and 64. If the DRIVES option is not specified, a
default of 1 drive is used.
Examples
To perform a parallel READALL to two backup devices:
>READALL *T;DRIVES=2
To perform a parallel READALL to three backup devices:
>READALL *T;DRIVES=3
Notes
•
If using the DRIVES option in combination with the AUTOREPLY option, the DRIVES option must be
specified before AUTOREPLY.
•
The DRIVES option may not be specified in combination with the APPEND option; otherwise, the command
is rejected.
•
In earlier releases of BACKUP+, the DRIVES option was called TAPES.
Option: LABEL
Validates the volsetid specified against the volsetid in the BACKUP+ tape label; prevents READALL if they do
not match. By default, the BACKUP+ tape label is not checked.
Syntax
>READALL ...;LABEL=volsetid
