ResetTPRLO Parameter

[David Ell]

I have a Win2K AS Cluster with HSG80 storage and a Tape Library w/ Drives connected via Fibre. I have one zone for the cluster/hsg80 and one for the cluster/tape library&drives.

When the cluster fails from one node to another it causes the Tape Library/Drives to fail by "downing" the tape drives..

What should the ResetTPRLO, EmulexOption, and ResetFF parameters be set to?

**Current Config**
Win2k AS SP3
LP952: 5-4.82a9/3.82a1
8.7 PlatformKit
SecurePath 4.0A
HSG80: 8.7P-3
Brocade12000(Core2/64) 4.0.2b

Thanks!

The settings down here are for the latest driver (a16) which is available on the HP site.

CPQkgpsa.sys v5-4.82a16 for Windows 2000 or
Lp6nds35.sys v4-4.82a16 for Windows NT
with HSG or EVA attached, optionally with EBS (SAN-Tape-Backup):

Enabledpc=1;
queuetarget=1;
queuedepth=25; -> 15 for > 4 Nodes
Topology=1;
NodeTimeout=10; -> if no Secure Path: 60
LinkTimeOut=40;
HLinkTimeOut=5;
ElsRetryCount=6;
SimulateDevice=1;
ResetTPRLO=1; -> MUST be 1 or 2;
2 is preferred when EBS* present
EmulexOption=0xAA00; -> 0xAA00 for Windows 2000 SP2 and NT
0xBA00 for Windows 2000 SP3 & up
ErrRetryMax=0;

* 'EBS present' means Tape Libraries connected to the SAN
through MDR/NSR Fibre Channel to SCSI Routers.
