General Troubleshooting for Universal Volume Manager
Remove the error and retry the operation.
The reason for the error could be as follows:
The switch is off.
An error occurred in the switch.
The cables are not properly connected.
Configuration in the external storage system is altered, and the specified
external volume has already been deleted.
An error on the external volume in the external storage system has occurred.
The path has been changed in the external storage system.
The port attribute of the local storage system has been changed.
The topology information has not been properly set.
Remove the error and retry the operation. The reason for the error could be as
follows:
The number of mapped volumes exceeds the maximum number (63,232)
available for the local storage system.
There are not enough LDKC:CU:LDEV numbers available for external volume
mapping.
1. The factors listed in the first row of Table 8-1 (Error: The Storage Navigator
computer cannot access to the external volume) could also be the factor of this
error. Check the factors of the first row, remove the error and retry the operation.
When the error still remains, try step 2.
2. Try the following procedures. If the following procedures do not work and the
path is not restored, call the Hitachi Data Systems Support Center.
Confirm that the cable between the local storage system and the external
storage system is connected properly.
When the cable between the local storage system and the external storage
system is connected properly, disconnect it once and connect it appropriately
again. After 30 seconds, check the path status from Storage Navigator.
The following show the description on the path statuses that are displayed in the
Status column in the Mapping Path Information dialog box and the reactions for
them. The notes on connecting each storage system as an external storage system
are in Connecting External Storage Systems. See
Systems
for settings of connection and examples of recovery procedure, and then
take corrective actions.
