2 Troubleshooting This section includes resolutions for various error conditions you may encounter. If you are unable to resolve an error condition, ask your HP support representative for assistance. Error conditions Depending on your system configuration, you may be able to view error messages (R-SIMS) as follows: • In XP Remote Web Console (Status tab) • In XP Command View (Event History or Event Notification panels) Table 5 Error conditions Error condition Recommended action The logical devices are not recognized by the host. Verify the following: • The READY indicator lights on the disk array are ON. • Fiber cables are correctly installed and firmly connected. • The target IDs are properly configured. The LUNs for each TID must start at 0 and continue sequentially without skipping any numbers. • The TIDs/WWNs on each bus are unique. Do not install two devices with the same ID on the same bus. Recheck the buses for new devices. • LUSE devices are not intermixed with normal LUNs on the same port. • The maximum number of LUSE devices per port has not been exceeded. • The disk array host mode is set correctly. • The data in the emx_data.c file correctly maps each WWN to a TID between 0 and 7. The host does not reboot properly after hard shutdown. If you power off the host without executing the shutdown process, wait three minutes to allow the disk array's internal timeout process to purge queued commands. If the host restarts while the disk array is processing queued commands, the host may not reboot successfully. Physical volumes cannot be created. Verify that the disk array logical devices are correctly formatted. Logical volumes cannot be created. Verify that the volume capacity for OPEN-x volumes is not greater than the maximum capacity allowed. See "Disk array supported emulations" on page 29 for capacities. Verify that the capacity of the volume group is not less than the total capacity of the partitioned logical volume. A file system cannot be created. Verify that logical volume name is a character-type volume. XP Disk Array Configuration Guide for Tru64 UNIX 23

This section includes resolutions for various error conditions you may encounter.
If you are unable to resolve an error condition, ask your HP support representative for assistance.
Error conditions
Depending on your system configuration, you may be able to view error messages (R-SIMS) as follows:
•
In XP Remote Web Console (Status tab)
•
In XP Command View (Event History or Event Notification panels)
Table 5 Error conditions
Recommended action
Error condition
Verify the following:
•
The READY indicator lights on the disk array are ON.
•
Fiber cables are correctly installed and firmly connected.
•
The target IDs are properly configured. The LUNs for each TID
must start at 0 and continue sequentially without skipping any
numbers.
•
The TIDs/WWNs on each bus are unique. Do not install two
devices with the same ID on the same bus. Recheck the buses for
new devices.
•
LUSE devices are not intermixed with normal LUNs on the same
port.
•
The maximum number of LUSE devices per port has not been ex-
ceeded.
•
The disk array host mode is set correctly.
•
The data in the
emx_data.c
file correctly maps each WWN to
a TID between 0 and 7.
The logical devices are not recognized
by the host.
If you power off the host without executing the shutdown process,
wait three minutes to allow the disk array's internal timeout process
to purge queued commands. If the host restarts while the disk array
is processing queued commands, the host may not reboot successfully.
The host does not reboot properly after
hard shutdown.
Verify that the disk array logical devices are correctly formatted.
Physical volumes cannot be created.
Verify that the volume capacity for OPEN-x volumes is not greater
than the maximum capacity allowed. See “
Disk array supported
emulations
” on page 29 for capacities.
Verify that the capacity of the volume group is not less than the total
capacity of the partitioned logical volume.
Logical volumes cannot be created.
Verify that logical volume name is a character-type volume.
A file system cannot be created.
