How to troubleshoot an SWXCR on an Alpha 2100

[Victor Mendham]

We are trying to troubleshoot a SWXCR on an Alpha 2100. If anyone has any experience working with these and/or has documentation they could share, please contact me

[Ian Miller.]

can you describe the problem?

Which version of VMS ?

Have you installed SWXCRMGR on VMS?

[Lawrence Czlapinski]

Victor, yes we have experience working with SWXCR. Can you give more details about the problems you are having? Is this a new RAID installation or a problem with a RAID set that has been operational?
1. In the Raid Configuration Utility (RCU), verify that the (controller) firmware is 2.70 or later, or that it is the latest available for your raid controller(s). We had problems with raid controllers not having a late enough version to work with our disks.
2. Documentation we have is "StorageWorks RAID Array 200 Online Management Utility for OpenVMS AXP User' Guide", part number is AA-Q6WVB-TE. You need a copy of this manual. It gives some procedures for managing RAID Arrays which can be several hundred words each.
3. Is this a new RAID installation?
4. Do you need to prepare a new or replacement Logical RAID drive as the System Disk? If yes, you will need the procedure for preparing a logical RAID Drive as System Drive for Shadowing. We prefer to use the local StorageWorks bricks rather than RAID for Systems disks.
5. Do you need to prepare a new or replacement Logical RAID Drive as a Data Drive for a Shadow Set?

Victor, if you power the controller off and back on you will need to do a fail and a mkopt for each disk:
$ swxcr fail dr'ctrl''unit' 'tower0' 'unit'
$ swxcr fail dr'ctrl''unit' 'tower1' 'unit'
$ swxcr fail dr'ctrl''unit' 'tower2' 'unit'
$! at our site, the dr unit numbers and the tower unit numbers all match. We have 3 disks in each logical drive.
$! for each controller, where ctrl is controller: "A","B", etc.
$! ex:
$ swxcr fail dra0 0 0
$ swxcr fail dra0 1 0
$ swxcr fail dra0 2 0
$! where unit is your logical drive number
$! then
$ swxcr mkopt dr'ctrl''unit' 0 'unit'

Thanks for all the help, unfortunately the problem wasn't mine, but a buddys who never got back to me about the exact problem.

I think he used the part number to get a manual and fix the problem.

So Thanks for all the help and points will be assigned.
