[Info-vax] Using MSA$UTIL to online maintain logical disk units?

[Rod Regier]

I'm trying to use MSA$UTIL to perform maintenance action on a failed JBOD unit.
Config is V/I64 (remastered) 8.4 w/patches, RX2600, SA6402 controller and front-access disks.
Unit 0 is a RAID mirror set
Unit 1 is a JBOD

36G Disk of JBOD failed, replacement hot-swapped into slot.

n.b. Next time around I'll try SCAN ALL and ACCEPT UNIT 1,
     but that ship has already sailed.

It would appear I'll be forced to recreate the UNIT offline,
any other online option ideas?
