MSL2024 direct connect to rx2800i with AD221A?

[Paul Dudson]

Hi. Running OpenVMS 8.4 with fibre/Scsi patch and can see the tape drive as $2$MGA0: when connected via a SAN switch. But want to run tape as a direct connect. Can set the MSL2024 into loop mode, and after direct connect to server can see the device from SDA FC, but device is invalid. Subsequent init/mount timeout. Is there a way or utility to change the mode on the AD221A for loop rather than point to point (fabric mode).

Hi,

What is the output of MC SYSMAN IO LIST_WWID? This command lists all tape device WWIDs that are not yet configured on FC. Are there any such ID? If yes, try executing MC SYSMAN IO AUTOCONFIGURE. This command connects the device and loading their drivers.

$ MC SYSMAN
SYSMAN> IO LIST_WWID
SYSMAN> IO AUTOCONFIGURE
SYSMAN> EXIT
$

Hi,

In my previous response I specified IO LIST_WWID. Instead IO LIST_WWID use IO_FIND_WWID. IO_FIND_WWID probes all Fibre Channel ports and detects all undiscovered tapes. To configure newly attached FC tapes, use IO_FIND_WWID command prior to running the IO AUTOCONFIGURE. The exact set of commands are as below. Please refer online help for more details.


$ MC SYSMAN
SYSMAN> IO_FIND_WWID
SYSMAN> IO AUTOCONFIGURE
SYSMAN> EXIT
$

Sorry for the confusion.

Regards,
Ketan

When the MSL2024 is connected via fabric switch to the server:-

but when I reconnect as a direct connection
MSL2024 shows the port as connecting....:-

So paths are still there from the fabric mode connect, and WWID can be seen, but no where to change the mode to loop for the direct connect on the server HBA end.

I don't think that directly connecting that tape library is supported.

IIRC loop mode FC is not supported either.
