5 Troubleshooting

Troubleshooting Volume Security

The Error Detail dialog box (Figure 22) may appear when you attempt to apply security settings. The probable causes of the error are:

•Some hosts in one security group are accessing volumes in another security group.

•Some hosts do not belong to any security group, but the hosts are accessing volumes in a security group.

To remove this error, you must find the hosts and the volumes that cause the error. To find them, take the following steps:

1.In the Error Detail dialog box, click the arrow button at the right end of the Host drop-down list.

•If the drop-down list displays only one entry, only one host is causing the error.

•If the drop-down list displays two or more entries, two or more hosts are causing the error.

2.Select a host from the Host drop-down list.

3.Right-click the arrow button at the right end of the CU drop-down list, and then check how many CU images are displayed in the drop-down list.

•If the drop-down list displays only one entry, the table displays all the volumes that are causing the error.

•If the drop-down list displays two or more entries, some of the error-causing volumes are dis- played in the table. To view other error-causing volumes, use the CU drop-down list to specify another CU image.

4.If two or more hosts are causing the error, repeat steps 2. to 3.

If error-causing hosts and volumes are detected, do either of the following to remove the error:

•Vary the error-causing volume offline from the error-causing host. For detailed information about varying the volume offline, see the documentation for host commands.

•Find the security group that contains the error-causing hosts and the error-causing volumes. Next, disable the security settings of the security group (see “Disabling Volume Security” on page 58).
