W2k3 and SQL 2K problems in clustered environment

[DragomirAtea]

Hi folks!

I've run into a veird problem at a customersite...

Here comes the HW setup.

Servers
2 DL740 G2 each server configured as follows.
8 * 2,7GHz 2MB Cache CPU
32 GB RAM (Usable)
2 * 72 GB (internal RAID1) for OS
2 * FCA 2408
Windows 2003 Enterprise
Microsoft SQL 2000 Enterprise
Configured in a Active/Passive MS Cluster

Storage
HP EVA 3000 2C4D (VCS 3.020)
ZDBDiskgroup (16 * 146GB)
DataDiskgroup (24 * 300GB)
2 * HP StorageWorks 2/16 EL switches
SecurePath 4.0C SP1
BusinessCopy 2.3

All vdisks presented i s VRAID 1

Now to my problem...

Lets say that nod1 is active, it holds all cluster resources. everything works just fine, no performance troubles what so ever...

But!!!

If I power down the passive node (node2) the performance on the active node drops lika a rock. I can barely log on to it and the users complains about responstimes.

How can a powerdown of the passive node effect the active node like that???

Any ideas, because I'm lost...
