Troubleshooting

Problems and solutions

This section contains known problems and solutions.

Problem 1

Problem 85340 — Disk manager Rescan Disks does not find

MetaLUNs. Windows 2000 requires an OS reboot to size (discover)

MetaLUNs. A conventional LUN is sized successfully with a Rescan

Disks.

Solution Upgrade to the latest adapter driver. This was corrected in 2.20a12

and later drivers.

Problem 2

EMC Knowledge base solution emc67559 — Fibre Channel tape

devices disappearing under Windows 2000.

Solution Upgrade to the latest adapter driver. This was corrected in 2.21a0 and

later drivers.

Problem 3

EMC Knowledge base solution emc69097 — If using adapters

connected to both VNX series or CLARiiON SPs, without PowerPath

installed, duplicate LUNs will be visible in the Device Manager and

Disk Manager. Only one instance of the LUN will be accessible, and

all other matching mappings will be listed as Unknown, Unreadable,

and Unallocated.

Solution This is normal behavior when multiple paths are available,

PowerPath is not installed, and the initiator type is registered in

PowerPath mode (array default depending on core code revision).

Problem 4

EMC Knowledge base solution emc70952 — While attempting to

install the Emulex HBAnyware Application Kit without removing a

previously installed Emulex HBAnyware Application Kit, the host

may generate the following error:

STOP 50 (PAGE FAULT IN NON PAGED AREA).

Solution Uninstall any existing HBAnyware Application Kit before installing

an updated HBAnyware Application Kit. This problem was corrected

in the application kit contained in the driver package for 2.21a7 and

later drivers.
