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 might 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.

For information about the INITIALIZE DISK command, see the SCF Reference Manual

for the Storage Subsystem.

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.

Possible causes:

•

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 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 occurs

only 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 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 do not show that the link is up.

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.
