The following table lists potential error conditions that might occur during storage system installation on an HP-UX host and provides instructions for resolving the conditions. If you cannot resolve an error condition, contact customer support.
| Error condition | Recommended action |
|---|---|
| The logical devices are not recognized by the system. | Make sure the READY indicator lights on the storage system are ON. Make sure the FC cables are correctly installed and firmly connected. Verify that LUNs are configured properly for each TID. Run sr-probe to recheck the Fibre Channel for new devices. For HP-UX 11iv3 and later, verify that LUN 0 is defined as the Command Console LUN (CCL) and mapped to the server. |
| A physical volume cannot be created (PVCREATE command). | Ensure the storage system devices are properly formatted.
Ensure the character-type device file exists. Ensure the correct character-type device file name is used with pvcreate. |
| A volume group cannot be created (VGCREATE command). | Ensure the directory for the new volume group exists. Ensure the control file exists. Ensure the correct major # (64) and minor # are used with mknod. Ensure the block-type file exists and is entered correctly with vgcreate. Ensure the physical volume is not already allocated to another volume group. |
| A logical volume cannot be created (LVCREATE command). | Ensure the specified capacity is not greater than 4096 MB.
Ensure the capacity of the volume group is not less than the capacity of the partitioned logical volume. |
| File system cannot be created (newfs). | Ensure the character-type device file is entered correctly with newfs. |
| The file system is not mounted after rebooting. | Ensure the system was restarted properly. Ensure the auto-mount information in the /etc/fstab file is correct. |
| The HP-UX system does not reboot properly after hard shutdown. | If the HP-UX system is powered off without executing the shutdown process, wait three minutes before restarting the HP-UX system. This allows the storage system internal time-out process to purge all queued commands so that the storage system is available (not busy) during system startup. If the HP-UX system is restarted too soon, the storage system will continue trying to process the queued commands and the HP-UX system will not reboot successfully. |
