Which of the two problems do you mean?  The database restore problem, with disabled array accelerator?  I solved it by removing the named-pipe alias, needed to install MS SQL 2000 server as another instance on the second node without sp3.   (I forgot to remove it after I install the second instance).  Or do you mean the enabled array accelerator problem with MS SQL intensive I/O?  (WIndows intensive I/O, with the same Disk Bytes/sec counter worked fine) 

?
