Troubleshoot the Disk Configuration

If you receive errors when you try to start the DISK object, go into the OSM Event

Viewer, specify Real Time, and view the service log ($ZLOG). ($ZLOG has the lowest-

level errors.)

Error -2 or 190

If the file system returns an error -2 or 190 when you issue the START DISK

command, you may need to initialize the disk by using the INITIALIZE DISK command.

You need to initialize the disk if the LDEV has never been used by the NonStop server

before or if the LDEV has been used by another host operating system.

See the SCF Reference Manual for the Storage Subsystem for information about the

INITIALIZE DISK command.

If you initialize the disk, issue another SCF START DISK command to start the disk

volume.

Error 66

If the file system returns an error 66, the FCSA cannot see the ESS or FC-switch port.

This could be caused by one of the following:

•

The SAN zone has not been set up correctly to include the FCSA and ESS WWNs

or ports. This mistake appears as “FC Device Unavailable” in the OSM service log.

(FC Device Unavailable means that the port on the ESS did not respond.)

•

You have specified an incorrect ESS port WWN in the SCF ADD DISK command.

This mistake appears as “FC Device Unavailable” in the OSM service log. (FC

Device Unavailable means that the port on the ESS did not respond.) This error

only occurs if the LUN is not configured for the port or the host group on the ESS.

If the LUN exists, symptoms other than error 66 occur.

•

You have specified an incorrect LUN in the SCF ADD DISK command. This

mistake appears as “Illegal request for the disk” in the OSM service log.

•

The Fibre Channel cable from the FCSA is connected to the wrong place or is

broken. If it is broken, the lights by the FC port will not show that the link is up.

You should also consult the OSM Event Viewer for other events and the recommended

action need for their repair.

Caution. If the LDEV has been used by a NonStop server before and you initialize the disk, all

data on the disk image will be lost.
