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).
