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:
1.
Log into Command View VLS.
2.
Select the System tab.
3.
In the navigation pane, expand Chassis.
4.
In the navigation pane, select Disk Arrays.
5.
In the task bar, select Service.
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 and Update Firmware
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.
•
Online, Fault Tolerant, some disks down — The virtual disk is online and fault tolerant. However,
some of the drives are down.
•
Online, Fault Tolerant — The virtual disk is online and fault tolerant.
•
Offline, either due to initialization or because disks are down and data may be lost — The virtual
disk is offline either because of initialization or because drives are down and data may be lost.
•
Critical, Quarantined due to missing disks — The virtual disk is in a critical state and has been
quarantined because three or more drives are missing.
•
Offline, Quarantined due to missing disks — The virtual disk is offline and has been quarantined
because three or more drives are missing.
•
Online, Not Fault Tolerant — The virtual disk is online and does not have fault tolerant attributes.
•
Unknown — The state of the virtual disk is not known.
Possible background activity running on the virtual disks:
•
Disks Scrubbing — Disks within the virtual disk are being scrubbed.
•
Expanding — The virtual disk is being expanded.
•
Initializing — The virtual disk is initializing.
•
Low-level formatting — A low level format is in progress.
