Troubleshooting for XP External Storage
If you have a problem with the Remote Web Console computer or Remote Web Console software, see the HP StorageWorks XP24000/XP20000 Remote Web Console User Guide for troubleshooting information.
Table 31 (page 126) provides general troubleshooting instructions for the XP External Storage operations. If you need to call the HP technical support, see “Calling HP Technical Support” (page 131) for instructions.
Table 31 General Troubleshooting for XP External Storage
Error
The Remote Web Console computer cannot access the external volume.
Corrective Action
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.
The external volume cannot be mapped as an internal volume of the local storage system.
The path to the external volume is blocked.
The path status that requires the reaction appears in the Mapping Path Information dialog box (see “Mapping Path Information Dialog Box” (page 86).
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 31 (page 126) (Error: The Remote Web Console computer cannot access the external volume) could also be the reason for 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 HP technical support.
•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 Remote Web Console.
See “Troubleshooting the Mapping Path” (page 127) and perform the required action.
