OpenVMS tape drive device Initialization

[CO_5]

When a tape drive was pulled out accidentally, and when it was inserted back to the slot, the SHOW DEVICE could not detect anymore the device name. How to recover this device name ?

I checked there was IO Connect command under SYSMAN.

For example: the tape drive is MKA600:

Since there is a NOTE saying abt Caution when using IO Connect, I wnt to make sure it is safe to use this command below:
IO CONNECT MKA600:

May i also know the proper way to disconnect the drive ?

Thank you.

I would try a SYSMAN IO AUTO /LOG to let SYSMAN rscan the buses.

Fro the help:
This command is for use on Alpha and I64 systems. It automatically
identifies and configures all hardware devices attached to a
system by connecting devices and loading their drivers.

On VAX systems, use the SYSGEN command AUTOCONFIGURE.

Pulled out of what? In what is this slot?

Generally (assuming that you're on a non-VAX),
MCR SYSMAN IO AUTOCONFIGURE is pretty
harmless. You can add /SELECT = MKA600
if you wish to limit it to the one device.

hi,

Initially, i did the IO AUTOCONFIGURE ALL. The device name $mka600: is still not visible on the SHOW DEV.

Now, i performed the IO AUTOCONFIGURE/LOG
and followed by IO AUTOCONFIGURE/SELECT=$MKA600:

It still did not show any sign of it.

Not sure what happened ? The tape drive was unplugged from a primary machine and reconnected back to the machine.

Apparently not.

Was the SCSI ID changed?

It might help to know to what you're
connecting the tape drive, and how.

There is a scsi cable connected to the machine and a power cable from the drive connected to the power line switch.

I am not sure how it was unplugged earlier by a personnel. But, it seems ok with the connection. There is no change in SCSI number.

CO,


The tape drive was unplugged from a primary machine and reconnected back to the machine.

"Primary machine"?
Is this perhaps a cluster config?
Are you issuing the tape commands from another node as the node which has the tape-unit?
If so, is TAPE_ALLOCLASS non-zero?

In general:
-what configuration?
-what version?

Proost.

Have one on me.

Hi,

What's the drive, (cable) and host bus adaptor model nos ?

J.

[Steven Schweda]

It _still_ might help to know to what you're
connecting the tape drive, and how.

What else is on the SCSI bus?

SHOW DEVICE DKA
SHOW DEVICE MKA

Are any of those devices working?

Termination?

If you can shut the system down, SHOW DEVICE
at the SRM console might be interesting.

Hi Guys,

thks for ur prompt replies.

The model of tape drive is SDLT 320.

It is connected to the primary node of a cluster(2 nodes) system.

i tried the IO autoconfigure/select=$mka600: from both nodes. It seems not much help either.

Btw, how do i know if TAPE_ALLOCLASS is non-zero?

Thks.
