Bus resets in SAN fabric environment

Hi

We have problem with scsi bus reset. In our case, some time, our
Compaq tru64 cluster and our Windows cluster send SCSI BUS RESET.
(see extract below)

/var/adm/messages.1:Jul  4 03:55:46 rosalie root: [ID 702911 daemon.notice]
NetWorker media: (info) EEI bus/device reset detected on /dev/ntape/tape2_d1
/var/adm/messages.1:Jul  4 03:55:50 rosalie root: [ID 702911 daemon.notice]
NetWorker media: (info) EEI bus/device reset detected
on /dev/ntape/tape2_d1 at opening. Rewinding tape

Question:
=========
- we use a FC to SCSI router to connect our librairy. Is there a router on
the market who can filter "SCSI BUS RESET" to prevent the tape drive from
rewinding by mistake?

Our kit is:
===========
Compaq SAN (3 switch,1 SCSI router 2FC->4LVD)
SUN e250 as Legato server DDS (SAN attach),(2 Compaq "jni" HBA)
Compaq tru64 cluster as SAN storage node and DDS, (2 Compaq "emulex" HBA)
Widows 2000 as SAN storage node and DDS, (2 Compaq "emulex" HBA)
Widows 2000 cluster as SAN storage node and DDS, (2 Compaq "emulex" HBA)
Widows 2000 cluster as SAN storage node and DDS, (2 Compaq "QLOGIC" HBA)
2 library STK L80 with 4 SDLT drives "LVD"
