Table 31 General Troubleshooting for XP External Storage (continued)

Error

The volume in the external storage system cannot be found even after the port discovery or the volume discovery was performed.

The external volume is blocked.

Corrective Action

Perform the required action and retry the operation. See “Troubleshooting Volume Discovery” (page 130) for the causes of the error.

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 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.

The Disconnect Subsystem command or the Disconnect Volume command is executed, but the progress status information is not updated.

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.

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 message of INTERVENTION REQUIRED is issued to the mainframe host as the device status.

The message of DEVICE ERROR is issued to the mainframe host as the device status.

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.

See the error description “The external volume is blocked.” in Table 31 (page

126)for the corrective action.

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

Status

Description

Unknown

The status of the path is unknown.

Blockade

The external port is blocked.

Action

The status of the path cannot be identified. Call HP technical support.

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.
