on a NetWare 6.5 sp7 we want to do mirroring. (nssmu version: 3.26 build 1062)

It's a HP ProLiant ML3 Server with 2 Maxtor 6L080M0 discs inside.

We tried it after installation, but the server slowed extremly down if we activate the mirror in nssmu.

With only one disc the server runs normal. We also tried a third Maxtor disc - same problem.

What's our problem?
