Operation
DISCUTIL Commands
At the discutil> prompt, you may enter any of the following commands:
The remainder of this chapter describes each of the commands. Remember that these
commands, though they may appear similar to MPE/iX commands or the commands used
with other utilities, operate only as described here.
CONFIGURE
The CONFIGURE command is used to dynamically add or configure new/additional devices
into the current configuration. You may access only configured devices with DISCUTIL.
NOTE
By default, DISCUTIL configures the system console, a tape drive, and all
disks indicated as being mounted in MPE XL tables. For this reason, you need
not use the CONFIGURE command on any of these devices.
To invoke the CONFIGURE command enter:
discutil>CONFIGURE [LDEV=]
ldev
[CLASS=]
devclass
[PATH=]
path
For example:
discutil>CONFIGURE 21 DISC 6/4.0.0
CONFIGURE Configures additional devices. (The system console, all disks thatwere mounted
at the time of the failure, and the tape drive are configured by default.)
