OpenVMS tape drive device Initialization

[CO_5]

Btw, a check on the sys$config.dat file.

The device is as below.

device = "SCSI Tape Class"
name = MK
driver = SYS$MKDRIVER
adapter = NONE
end_device

[CO_5]

I tried not to shutdown the server if there is manual way of initializing this drive. Reboot of the server will be my last option.

SH DKA or MKA , gave no such devices available.

Is this the only device connected to this host bus adaptor ?

SDLT320 are LVD, is it a single drive or in a library ?

Try a $ SHOW DEVICE/FULL PKA0 .. does it say LVD SCSI ?

LVD (low voltage diff)... It's possible that if you've connected the drive without powering off from the HBA end, you could have damaged the HBA card.

Do you know what model the HBA is ? Is it a 3X-KZPCA-AA ?

I guessed that. It's harder to guess:

What model computer(s)?

Connected how?

What model SCSI adapter(s)?

Connected to what? How?

If the device was MKA600 before you
disconnected it, and if it was connected
directly to a SCSI card in one system, then
it should still be MKA600 when you reconnect
it. But in that case, the device would not
disappear when you unplugged it. (Unless you
rebooted the system.) Are you sure that
MKA600 was its original name?

If it's installed in some smart box instead
of being connected directly to a SCSI card,
then it could all be more complicated (and I
would know less about what to do).

If you would describe all your equipment and
how it's all connected, this might be much
less painful.

$ SH DEV/FULL PKA0

Device PKA0:, device type SYM53C895 LVD SCSI, is online, error logging is
enabled.

Error count 0 Operations completed 336
Owner process "" Owner UIC [SYSTEM]
Owner process ID 00000000 Dev Prot S:RWPL,O:RWPL,G,W

HBA ? I need to check this.

Hello guys,

after some try n errors, there are still no clue how this IO AUToconfigure THING does not work. After reboot the system, it appears online again.

One more last question: How do i bring a device like this tape drive offline ?

So, pls close this case.

I am not sure that I understand what you are really asking here, but you can make the drive unavailable to the system, as show below.

SET

DEVICE

/AVAILABLE

/AVAILABLE
/NOAVAILABLE

Controls whether the specified disk or magnetic tape is to be
considered available. You must dismount the specified disk
or magnetic tape before entering the SET DEVICE/[NO]AVAILABLE
command. If you specify the /NOAVAILABLE qualifier, any attempt
to allocate or mount the specified disk or magnetic tape is
prevented. Devices are automatically set /AVAILABLE when brought
online even if the device had been previously set /NOAVAILABLE.
