The Setup→ Device→ IDs command is available while viewing a
partition. Use this command to set the SCSI ID for a SCSI-attached drive
or the Loop ID for a Fibre-attached drive. All hosts that view the drive will
see the same SCSI ID associated with the drive.
The Setup→ Device→ Access command gives you access to the Channel
Zoning, SCSI Host, FC Host, SNW Host, SNW Drives, and LUN
Mapping Wizard commands, which are available while viewing the
physical library.
•Use the Channel Zoning command to restrict host access to
particular I/O blade ports.
•Use the SCSI Host and FC Host commands to configure access to
partition accessors and drives on a per-host basis. If you have
connected your host to either the FC port or the SCSI port on the
MCB, or to a port on one of the I/O blades, you must map the
appropriate partitions by using either the SCSI Host command or the
FC Host command. If you have connected your hosts directly to the
drives, use third-party software of your choice to manage media from
the host itself.
• Use the SNW Host command to create, modify or delete access to the
Storage Networking (SNW) drives configured in the library.
• Use the SNW Drives command to select the drives you want
managed by the Storage Networking (SNW) feature. The drives
selected can be configured so client hosts can be granted or denied
access. Only HP LTO-5 generation or later drives are supported. Each
drive selected will consume a SNW license.
• Use the LUN Mapping Wizard command to set up LUN Mapping for
your fiber channel hosts
If you have not otherwise restricted access, SCSI Host has full control of
all LUNs on all FC and SCSI channels, up to an overall system total of
2,048. SCSI hosts can configure access at the LUN-level for an overall
system total of up to 2,048 LUNs.
If you have not otherwise restricted access, FC Host has full control of all
LUNs on all FC and SCSI channels. Each FC host can be configured to
access a maximum of 255 LUNs, up to an overall system total of 2,048.
