Scalar i6000 Host Access

To use host access, you need the following:

• A Path Failover/Native Storage Networking license on the library
• Drives licensed for Storage Networking
• To add a partition to a host access group, the partition must have its control path via a SNW drive
• Hosts configured
• Host access groups configured

A host access group is composed of at least one host and one drive. Each host in the access group can send read/write commands to the drives in the group, and can send move commands to the partitions in the group. A host can only be in one access group. Drives and partitions can be in multiple access groups.

List all available access types and any current configuration details.

Lists all the configured parameters for any highlighted access group.

Shows a summary of the total number of access groups, mapped or unmapped as well as what available hosts are assigned or unassigned.

Provides options for drive configuration, maintenance and action.

Note: Host access controls are only available on HP LTO-5 and LTO-6 drives.

The Add features allows you to perform two, distinct tasks:

• Create a Host Access Group
• Configure a host

All hosts that are zoned or directly connected to the drives are available to be assigned to host access groups. You may wish to modify existing hosts to make their names more “user friendly” for when you add them to access groups. You may wish to delete hosts that are not connected to the SAN. Using the host configuration option, you can do the following:

You can add hosts that are not currently connected to the SAN (i.e., “prep” your library for a future host). These are hosts that you plan to add to the SAN later, but want to pre-configure in host access groups now. If you don’t eventually add the hosts to the SAN, they will not be able to access the drives/partitions you choose. In most cases, you will not need to create hosts in this way.

1. From the Navigation panel, select Host Access.

2. In the Operations panel, click Add.

   

   Item	Description	Action

   Name	Allows you to enter a name for your new access group.	Enter text.
   Host	Allows you to configure and define any hosts that are connected to your library.	Select the radio button to add a host server.
   WWPN	Allows you to enter the unique world wide port name (WWPN) for an host connected to a SAN and zoned to the library. The string must be 8 hexadecimal numbers, a colon (:), and 8 hexadecimal numbers (########:########).	Enter text.
   Description	Allows you to add a unique identifier to your host server.	Enter text.
   Type	Allows you to select the operating system of the host.	Select an option from the drop-down menu.

This feature allows you to modify the name, type, port, or WWPN of a visible host. Unmodified hosts that are connected to the drive(s) have no predefined name and are named “Unknown” by default. You may wish to change the name to a more “user friendly” name to distinguish one host from another.

1. From the Navigation panel, select Host Access.
2. From the North Panel, select the access group you want to modify.

3. In the Operations panel, click Modify.

This feature allows you to delete hosts that are no longer connected to the SAN. You can only delete hosts whose state is offline (i.e., not connected to the SAN). Any time you delete a host you remove all host mappings configured for that host.

1. From the Navigation panel, select Host Access.
2. From the North Panel, select the access group you want to delete.

3. In the Operations panel, click Delete.
