Hi all

we have a 2node proliant cluster with dualchannel adapteccontrollers and
an infortrend
dualchannel scsi2ata external raid.

The Raidsystem has 2 logical drives with the follwing drive/channel/lun
configuration

Channel 0 ID 0 Lun 0 ->logical Drive 1
Channel 0 ID 0 Lun 1 ->logical Drive 2
Channel 1 ID 0 Lun 0 ->logical Drive 1
Channel 1 ID 0 Lun 1 ->logical Drive 2

I've connected channel1 of server1 to channel1 of infortrend and
terminated the channel
I've connected channel1 of server2 to channel2 of infortrend and
terminated the channel

In Netware6.5 (and in 6.0) I see FOUR devices on Server 1:
0x0013: [V321-A3-D0:0] Compaq 64-Bit Slot 0 Port 1 ID 0 IFT IFT-7250F [HDD]
0x001E: [V321-A3-D0:1] Compaq 64-Bit Slot 0 Port 1 ID 0 LUN 1 IFT IFT-7
[HDD]
0x003D: [V321-A3-D0:20] Compaq 64-Bit Slot 0 Port 1 ID 0 LUN 32 IFT IFT
[HDD]
0x003E: [V321-A3-D0:21] Compaq 64-Bit Slot 0 Port 1 ID 0 LUN 33 IFT IFT
[HDD]

and also on Server 2
0x0011: [V321-A3-D0:0] Compaq 64-Bit Slot 0 Port 1 ID 0 IFT IFT-7250F [HDD]
0x0019: [V321-A3-D0:1] Compaq 64-Bit Slot 0 Port 1 ID 0 LUN 1 IFT IFT-7
[HDD]
0x0038: [V321-A3-D0:20] Compaq 64-Bit Slot 0 Port 1 ID 0 LUN 32 IFT IFT
[HDD]
0x0039: [V321-A3-D0:21] Compaq 64-Bit Slot 0 Port 1 ID 0 LUN 33 IFT IFT
[HDD]

So I guess, the raid somehow mirrors channel 2 to high LUNS on channel 1
and vice versa?

Except for looking messy that would not be a problem, BUT:

if I create a partition on V321-A3-D0:1 and a shared pool USER on that
partition it appears
as a SECOND POOL WITH THE SAME NAME on V321-A3-D0:21

Those pools are not editable independently, if you delete/rename one,
you'll delete/rename both,
althoug one USER can appear as ACTIVE and the other as INACTIVE.

THAT is a problem for failover scripts, which fail and the resource goes
comatose.
The sympton only happens on partitions on logical drive 2 (with the LUN 1)
I have several other partitions/pools on logical drive 1 (LUN 0), which
behave normally.

I think my problem will be fixed, If I learn how to teach either the
Raidcontroller or the
adaptec inside the servers not to "see" the other channel.

-I have recreated the pool/partition from the scratch
-I did nss /poolverify and nss /poolrebuild
-I have NW6.5SP5 and the latest adpt160m.ham /LUN
-I have the latest firmware on the infortrend and on the proliants

Pooh, I had some very troublesome days/evenings/nights the last two weeks,
'cause guess
why the volume name is "USER"?
