Author SCSI disk going offline

One of my SCSI drives keeps going offline. When I connect to the system I find the drive in mount verification timeout. I can dismount the drive but any attempt to do anything with it results in "medium is offline", including attempting to access it with rztools. There are no errors logged against the device.

The disk comes back if I reboot the system but after having a few failures a couple of weeks apart it has now failed twice today.

Does anyone have any ideas of how I might be able to figure out why it's going offline?

I may have figured it out. I opened the system to check connections and ended up pulling the drives out. The top of this particular drive was very hot. I moved it to another bay where it could get some more airflow across it. I did some searching on Google and it appears page 13 (0x0d) of the log sense data may be temperature data. If that's true, the drive is operating very close to its cutoff temperature. I put a fan in front of the system where it will draw air out of the case across the top of the drive. According to rztools, it's cooling off.

Well, not quite fixed. I just checked on the system and the disk is down again.

I believe it's quite warm in NE USA at the moment

Someone with lots of Alpha experience told me to fit 'blanking panels' (don't know the correct term) over the unused disk drive slots ( for the 'bricks' ) in order to maintain air flow, rather than blowing it straight out of the machine.

I've been running my Alpha4000 continuously at about 380 W ( without monitor ) and the system temp. gets to a maximum of about 30 deg. C. (system shutdown 51 deg. C) The 4100 (4 CPU) takes nearly 800 watts.

My system is a PWS 600au. The disks are mounted internally, not in an expansion cabinet. The box doesn't have a whole lot of airflow through it. There's a fan on the processor that blows air across the CPU and out the front. There's another fan in the power supply. I think that's it. I have to try to get some more fans in the case. There's not much air flow across the drives at all.

No more VAX hobbyist licenses. Community licenses for Alpha/IA64/X86_64 VMS Software Inc. Commercial VMS software licenses for VAX available from HPE.

Just re-visiting.. No more hobbyist licenses? Is that from vmssoftware.com, no 'community' licenses?

I recall that the disks failed on the public access VMS systems that included Fafner

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

See the forum about licensing. Don't know if HPE hobby licenses still being issued. Commercial licenses still being sold.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
