Model 12h Disk Array problem!! Help!

[j kubler]

I have a Autoraid Disk Array 12h attached to an HP 3000 system. We got a yellow light on a disk and are awaiting a replacement disk tomorrow. The system has been operational but it hung tonight. Trying to do a memory dump it now says, "failed to initialize status = -7" and now the array says "balancing". The system now aborts with same prior to giving the same message and before ISL prompt. What recommendation can you give?
Thanks,
Jeff Kubler
