Re: OVMS 7.2.1 cluster with RA3000

Something I found in the cluster_config batch file: If you do not define port allocation classes later in this procedure for shared SCSI buses, all nodes sharing a SCSI bus must have the same non-zero ALLOCLASS value. If multiple nodes connect to a shared SCSI bus without the same allocation class for the bus, system booting will halt due to the error or IO AUTOCONFIGURE after boot will keep the bus offline. OpenVMS 7.1-2.

Re: OVMS 7.2.1 cluster with RA3000

Finally I received the hardware.

To configure a drive I put 2 x 18 GB drives into the 6-drive bay and then used
P00>> run bios pya0
to start the SmartArray 5300 bios in order to create a logical drive RAID-1. Everything ok.

But when I do "sho dev" at the console I don't see any disks. Only the controllers
dva0, dqa0, pka0, pkb0, pkc0, pky0.

Shouldn't I see some dk* devices?

There is a 1 GB NIC in addition to a dual port 100 MB Ethernet card. I can see eia0 and eib0, which correspond to the 100 MB card, but I cannot see the 1 GB Ethernet card. It also shows all LED's on at the back. Is that normal?

Unlike the DS20, the DS20E guide does not outline anything about using specific PCI slots for specific cards.

The following is installed.

Slot 1 - PBXGK-BB VGA (Elsa Gloria Synergy)
Slot 2 - DEGPA-TA Gigabit Ethernet
Slot 3 - 3X-DE602-BB Dual Ethernet 10/100
Slot 4 - KZPBA-CB Scsi Wide/diff
slot 5 - CCMAB-AA Memory Channel
Slot 6 - 3X-KZPDC-BE (SmartArray 5302/128)

Is there something wrong?

hi,

similar has cropped up before here, see if any thing in the following thread applies :-

Re: OVMS 7.2.1 cluster with RA3000

Although the card was in hose1, I did not set the BOOTBIOS pya0 SRM variable. >>> set BOOTBIOS pya0 >>> INIT did the trick. No I see a dy* drive. Thanks!

What about the 1 GB NIC? Will this work after the system is installed - initialized by a driver, etc?

Re: OVMS 7.2.1 cluster with RA3000

Sorry I forgot to also add this:

recommendation:

For VMS:
For systems using Gigabit Ethernet, increase system parameter NPAGEVIR by 1500K for each Gigabit Ethernet NIC in system.

Should work fine with the required SRM version, but I would update to the latest firmware all across the system and options.

Re: OVMS 7.2.1 cluster with RA3000

The SRM console sees the 1 logical drive from the SmartArray 5300, named "dy0", but the 7.2-1 installation does not see it. The SmartArray has firmware 3.56 which is newer than the one i have on the 6.8 firmaware cd (3.40) Any ideas?

hi,

did you set heap_expand 2mb ?

Re: OVMS 7.2.1 cluster with RA3000

BTW

OpenVMS support for the Smart Array 5300A was introduced in the OpenVMS Alpha V7.3-1 release. The following TIMA kit is required:

DEC-AXPVMS-VMS731_FIBRE_SCSI-H0200├в 4.PCSI

Full boot support from SA5300A logical volumes is provided in the supported Tru64 V5.1A and OpenVMS V7.3-1 operating system environments.

fwiw

Re: OVMS 7.2.1 cluster with RA3000

I cannot use 7.3-1 this time. So I will remove the SmartArray 5300 and put in some other normal Scsi controller. It should be good enough for its purpose. But I have another problem:

For RA3000 Pedestal (2 controller) I have the following configuration (working live cluster).

Node 1 - BN21W-0B (Scsi Y-splitter)
Node 2 - BN21W-0B (Scsi Y-splitter)
The inner ends of the Y split are connected together using BN21K-05 cable.
The outer ends of the Y split connect to each of the Controller's Host 0 in and Host 1 in using 2 BN38C-05 cables.

As far as I understand the above shows that the Nodes are in the middle of the SCSI bus and the HSZ22 controllers terminate each SCSI end. The KZPBA controllers inside the cluster nodes have termination resisters removed.


Unfortunately I'm missing the BN21W-0B Y-splitter cables/adapters. But I have rackmount RA3000 (2 controller) this time, which unlike the Pedestal version has Host 0 and 1 in and OUT.

Is it possible to configure a cluster storage with redundant controller by installing the RA3000 in the middle of the Scsi chain? I was wondering if it would work to terminate each adapter in the Nodes, connect Node 1 to controller Host 1 in, and Node 2 to controller Host 0 out. Then connect controller Host 1 out and Host 0 in together. Will this work?
