Table 4 Error conditions
Error condition
The logical devices are not recognized by
the host.
The host does not reboot properly after
hard shutdown.
Physical volumes cannot be created
(pvcreate).
Volume group cannot be created
(vgcreate).
Logical volumes cannot be created
(lvcreate).
The file system cannot be created (newfs
command).
26 Troubleshooting
Recommended action
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.
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.
Verify the following:
• The disk array logical devices are correctly formatted.
• The character-type device file exists.
• The correct character-type device file name is used with
pvcreate (for example, /dev/rdsk/...).
Verify the following:
• Tthe directory for the new volume group exists.
• The control file exists.
• The correct major number (64) and minor number are used
with mknod.
• The block-type device file exists and is entered correctly with
vgcreate.
• The physical volume is not already allocated to another volume
group.
Verify the following:
• The volume capacity for OPEN-x volumes is not greater than
the maximum capacity allowed. See
device emulations.
• The capacity of the volume group is not less than the total
capacity of the partitioned logical volume.
Verify that the character-type device file is entered correctly with
newfs(for example, /dev/vg01/r/vo/x).
