HP 9000 Virtual Library System - Manual (Page 122)

When a failure occurs, repair the failure. In most cases, the system will automatically recognize
that the repair is complete and restore the path or paths without having to reboot the system;
however, you may need to reboot the system if the repair includes installing a new USB LAN
adapter.
Managing Disk Arrays
Some VLS firmware versions allow you to manage the disk arrays. The disk array management
screens allow you to view the status and other details of a virtual disk, delete unused virtual disks,
and clear the metadata on leftover disks.
To access the disk array management screens, from Command View VLS:
1.
Select the System tab.
2. In the navigation tree, expand Chassis.
3. In the navigation tree, select Disk Arrays.
4. In the task bar, select Service.
The screen provides a caution about using the Disk Array Management service.
5. Click Accept.
The screen opens to the Manage Virtual Disks screen and displays details about the virtual
disk array including the disk array number and IP address, virtual disk name, total capacity,
free capacity, owning controller, RAID level, status, background array activity (and percentage
complete), and the serial number. You can access the Clear Leftover Disks, Update Firmware,
Reset Array Information, and Set RAID Mode screens from the task bar.
Viewing the Virtual Disk Status
The Manage Virtual Disks screen displays details about the virtual disks in the disk arrays. By
default, it lists all of the virtual disks in the arrays. You can narrow the list by using the Select Disk
Arrays list and then selecting Update.
The status of the disk array is one of the following:
•
Online, Not Fault Tolerant, some disks down — The virtual disk is online. However, some
drives are down and the virtual disk is not fault tolerant.
