Table 31 General Troubleshooting for XP External Storage (continued)
Corrective Action Error
Perform the required action and retry the operation. See “Troubleshooting
Volume Discovery” (page 130) for the causes of the error.
The volume in the external storage
system cannot be found even after the
port discovery or the volume discovery
was performed.
Remove the error and retry the operation.
The reason for the error could be as follows:
• All the set paths are blocked (paths are not connected).
•
The attribute of external volume is not set to Read/Write attribute.
• The external volume is blocked by error.
The external volume is blocked.
Click the Refresh ( ) command on the Remote Web Console main window
while the Status: Enable button is shown. If the device status remains as Checking
even though you have updated the information, execute the Check Paths &
Restore Volume command again.
If the same problem persists despite retrying, call HP technical support.
The Check Paths & Restore Volume
command is executed and you have
waited more than 10 minutes, but the
status of the device does not change
from Checking.
Click the Refresh ( ) command on the Remote Web Console main window
while the Status: Enable button is shown. If the progress information about the
Cache Destage status is not updated even though you have updated the
information, call HP technical support. The time required for the writing
processing of data from the cache to the external volume (destaging processing)
depends on the volume capacity (more time is required for the larger volume
than the smaller one). The processing speed is about 20 MB/s. However, the
processing speed depends on the performance and the status of the external
storage system.
The Disconnect Subsystem command
or the Disconnect Volume command
is executed, but the progress status
information is not updated.
The device status is currently changing. Wait for a while, and then check the
device status again. When the transition of the device status has completed
normally, the device can be used immediately. If the device is blocked as a
result of the device status transition, see the error description “The external
volume is blocked.” in
Table 31 (page 126) for the corrective action.
The message of INTERVENTION
REQUIRED is issued to the mainframe
host as the device status.
See the error description “The external volume is blocked.” in Table 31 (page
126) for the corrective action.
The message of DEVICE ERROR is
issued to the mainframe host as the
device status.
Troubleshooting the Mapping Path
Table 32 (page 127) shows 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. See “Connecting
External Storage Systems” (page 134) for notes on connecting each storage system as an external
storage system and for settings of connection and examples of recovery procedure, and then take
corrective actions.
Table 32 Mapping Path Statuses and Required Actions
Action Description Status
The status of the path cannot be
identified. Call HP technical support. The status of the path is unknown. Unknown
The external port is blocked because of
the microcode replacement or package
replacement or other factor. Check the
status of the local storage system. If you
cannot restore the path, call HP
technical support. The external port is blocked. Blockade
