Multiple Users; Hard Disk Replacement; Identifying A Failed Disk - HP StoreOnce B6000 Series User Manual

3. Apply the license using one of the following CLI commands:
license load <file-image> to load a license that has been saved as a file image. The
file image must exist in the Backup System's repository directory.
license add <string> to key in the license directly. If you used email or a temporary
file, cut and paste the string exactly as you obtained it from the HP Licensing website. It is not
advised to try and key in the LTU manually.
4. The key is specific to the HP StoreOnce Backup System couplet to which it applies. It cannot
be transferred.

Multiple users

The HP B6000 Management Console supports multiple GUI and CLI sessions. However, we
recommend:
No more than 8 active Operator sessions for the GUI
No more than 16 active Operator sessions for the CLI
No more than 1 active Admin session to ensure there is no confusion when configuration
changes are made
Currently, you cannot see which users are logged in. The accounts show command will list all
the user accounts defined for the HP B6000 Backup System. For each account the authority level
is provided.

Hard disk replacement

The HP B6000 Series Backup System uses RAID 6 storage devices. RAID 6 provides protection
against double disk failures and failures while a single disk is rebuilding. This means that one disk
can fail within each 6–disk array and the system will continue to function correctly. Once the failed
disk is replaced, the RAID rebuilds automatically.
RAID disks are used in the:
Server nodes: there are two disks in each node, which mirror each other. If one fails, the
system will continue to function correctly. The failed disk should be replaced as soon as
possible. The replacement disk invokes the Smart Array Automatic Data Recovery (ADR) feature
to rebuild the replaced drive.
Storage array controllers: each controller has two arrays, each with six disks. One disk may
fail in each array without affecting system functions. The failed disk(s) should be replaced as
soon as possible.
Capacity upgrade shelves: each shelf has two arrays, each with six disks. One disk may fail
in each array without affecting system functions. The failed disk(s) should be replaced as soon
as possible.

Identifying a failed disk

WARNING!
subsequent disk failure within the same array will result in complete data loss.
If you have configured recipients for email alerts on the GUI, they will be notified of a disk failure.
You can also use the GUI as follows:
Use the Hardware Problem Report to identify problems with a failed or failing disk.
It is important to replace a failed or predictive failed disks as soon as possible. Any
