HOWTO add disk on MPE

Start from hardware planning. Buy MPE supported disk. Consult with IODFAULT.PUB.SYS file contain supported disks. Verify that you have place for it, free connector on cable, free power connector. Consult with SYSGEN output about avaliable SCSI addresses.

The most quick way to add disk is its "blind" defining prior actual disk adding. Keep existing configuration to be able start with "known good" configuration in case if something will go wrong:

:SYSGEN
 sysgen> KEEP BCKCFG
 sysgen> EXIT

You can boot using this config by command ISL> START NORECOVERY CONFIG=BCKCFG

: SYSGEN

Reboot system with NORECOVERY option, you should see new device now. Use VOLUTIL to start use new disk
