Table 4 Device tabs continued (lower half of the page)
Interface Information tab
This is the device name, such as Medium Changer or Drive 1. There will be an entry for
each drive that is appropriate for the selected emulation type. Device Name
This is a unique serial number for the device. It is generated automatically by the HPStoreOnce
Backup System and cannot be edited. Device Serial Number
This is provided during manufacturing for all possible devices. You can change this, if
necessary, but not to any names that are in use by libraries or drives on the local appliance. World Wide Node Name
This is generated automatically by the HP StoreOnce Backup System for FC devices. You
can change this, if necessary, but not to any names that are in use by libraries or drives on
the local appliance. World Wide Port Name
If the library is FC attached, you can choose which port each drive is on using this selection. Port
iSCSI Authentication tab (iSCSI devices only)
Check this box if you require the initiator to logon. You must also provide the Initiator CHAP
user name and secret. Require initiator to logon
This should be the same CHAP user name that you configure for the target on the iSCSI
Initiator. (On the Microsoft iSCSI Initiator, this is the User Name as it is configured on the
Targets tab in the Log On to Target Advanced Settings.) Initiator CHAP User
Name
This should be the same CHAP secret that you configure for the target on the iSCSI Initiator.
(On the Microsoft iSCSI Initiator, this is the Target Secret as it is configured on the Targets
tab in the Log On to Target Advanced Settings.) Initiator CHAP Secret
Check this box if you require mutual CHAP authentication, which means that the target must
also log on to the initiator. You must also provide the target CHAP user name and secret. Target required to logon
to initiator
On the iSCSI Initiator you must also make sure that mutual authentication is enabled. (On
the Microsoft iSCSI Initiator, make sure Perform mutual authentication is checked on the
Targets tab in the Log On to Target Advanced Settings.)
This may be any meaningful CHAP user name. It does not need to match any information
on the iSCSI Initiator. Target CHAP User Name
This should be the same CHAP Secret that you configure for the target on the iSCSI Initiator.
(On the Microsoft iSCSI Initiator, this is the Secret as it is configured from the General tab.) Target CHAP Secret
NOTE: For more information about configuring the Microsoft iSCSI Initiator see the HP StoreOnce
Backup System Installation and Configuration Guide.
To edit device details
It is possible to edit some, but not all, device details after creating a device. In particular, you
should be aware of the following:
•
You can delete cartridges by reducing the number of slots on the Devices page, but this will
only remove the highest—numbered blank slots. Once the Delete operation reaches a slot
number that contains data, it will not allow you to reduce the number further on the Details
page, even if earlier slots are blank. You must first use the Cartridges tab to make the slot
blank.
•
If you change the cartridge size on this page, this will only change newly-added cartridges;
it does not change the size of cartridges that have already been created.
•
You can reduce the number of drives but, if you go to 0, the port setting will go to "No Port".
•
You cannot change the library type to a type that has a smaller set of maximum values (e.g.
number of cartridges) than is currently set.
