What do these two error messages mean in the following anal/error/elv output?
%ELV-E-B2TNOTFND, valid bit-to-text translation data not found
-ELV-W-NODNOTFND, bit-to-text node not found

we are getting an increased disk error count on VMS 8.3 when we use IBM SAN disks presented to the VMS system using an IBM SVC. Neither HP nor IBM seem interested in providing integrated support for configuration.

Re: anal/erro/elv translate/sin=6-jan/before=7-jan/full


B2TNOTFND, valid bit-to-text translation data not found

Facility: ELV, Error Log Viewer

Explanation: Valid bit-to-text translation data was not found for the entire current error log event. This could result from any
of the following conditions:

o Bit-to-text translation of the current error log event is not supported.

o An invalid error log event was encountered.

o There is an error in the bit-to-text translation data for the current error log event.

User Action: Verify that bit-to-text translation of the current error log event is supported. If it is supported, contact HP Customer Support.

Either way, I would have expected that HP would provide an analysis of the error log event if you have a maintenance contract with them. That said, I'd then expect it to be a "discussion" of whether they were the guilty party for the error or whether it was IBM.

Re: anal/erro/elv translate/sin=6-jan/before=7-jan/full

Can't help with the meaning of this output, but, here's a suggestion - if you have an AlphaServer with DECevent installed, copy the ERRLOG.SYS over to it and DIAGNOSE the file for disk events (DECevent should be able to handle disk issues even if it doesn't know anything about the system that encountered the issues).

Re: anal/erro/elv translate/sin=6-jan/before=7-jan/full

ELV was written by a member of VMS Engineering who worked in the "platform support" group -- that is, they were concerned with CPU or memory related problems. As such, it does not do a good job of dealing with errors from other components, like device errors.

Re: anal/erro/elv translate/sin=6-jan/before=7-jan/full


the only other 'supported' errlog analysis tool is SEA (System Event Analyzer), part of the WEBES tool suite. But I sincerely doubt, that it will do a good job at decoding SAN disk errors, DECevent is still the best tool for decoding SCSI related disk errors, which includes SAN disks.

Re: anal/erro/elv translate/sin=6-jan/before=7-jan/full

Clark, first and foremost, some details about your environment are necessary. Are your systems Alpha or Itanium? I read that you're using OpenVMS V8.3 This is current for Alpha but V8.3-1H1 is the latest release for Itanium. Your patches should also be the latest available, particularly when trying to debug issues with 3rd-party storage. There are other gory details like the firmware version for your HBAs, SAN switches and SAN switch type that are pertinent.

While I'm not an expert on IBM's SAN devices or their operation, MOST error logging at the host has limited value for any device that's more virtual than physical. Many SAN devices use a boatload of cache and the actual physical devices are highly "virtualized" making traditional error diagnosis painfully difficult. While you're certainly having a problem with the native error translation tool it's main use is not directed toward storage and others have said just that. SEA, mentioned before, is only available to customers with hardware maintenance contracts.

Even with the SAN devices that HP sells, the majority of the error-handling and analysis is provided by the controller and associated software that runs on PCs used to setup, control and manage the SAN devices. In HP's case this would be the EVA or XP controller and the SMA (Storage Management Appliance, I think). These implements are used to detect and analyze device failures proactively and reactively and present those errors for human intervention. I would expect IBM's devices to have similar solutions.

There are certain recommendations for configuring your SAN to work best with OpenVMS. If your OpenVMS systems are supported by HP that can help. There are general configuration guidelines for SAN devices and OpenVMS that should be somewhat standard. OpenVMS device drivers used to support connections to a SAN are standards-based but special configurations are required. The main one that I remember is that you should setup your SAN so the switches are zoned in a way that VMS can only see the controllers and vice versa. I think that's the main consideration.

You're also dealing with 3rd party devices and getting support if they're not working as expected can be difficult at best. I'm not aware that actual testing has been performed on IBM's SAN devices. Unfortunately each vendor seems to interpret standards in their own way and this can lead to problems. Differences in nomenclature can also bite you. What might be a clear recommendation to a site using a HP EVA controller might not make a lick of sense to someone trying to configure an IBM SAN controller. Switch configurations should be a little less ambiguous although there are certainly some switches that may have not been tested.

Re: **bleep**/erro/elv translate/sin=6-jan/before=7-jan/full

I have a similar situation. The only way to get all of the information in the log file for a disk error is to use the DUMP command in ELV. The problem with that is that I have not fould the file layout for the event log. I suspect that the layout may be different for different devices, but is there anywhere the file layout is documented?
