The IDs command is available from the physical library. Use this to set the Loop ID of a drive. All hosts viewing the drive will
see the same Loop ID associated with the drive.
FC Host and SCSI Host are available from the partition. Use them to configure access to partitions on a per-host basis. If
you have connected your host to either the FC port or the SCSI port on the MCB, you must map the appropriate partitions
with either FC Host or SCSI Host. If you have connected your hosts directly to the drives, use the third-party software of
your choice to manage your media from the host itself.
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 2048.
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 2048. SCSI hosts can configure access at the LUN-level for an overall system total of up to 2048 LUNs.
Setting Device IDs
From a partition you can change the Loop ID for a Fibre-attached drive. For example, the default Loop ID for a drive that you
are installing may conflict with the assigned Loop ID of an existing drive. You may be using an application that expects to
communicate with a device at a specific Loop ID, but that ID may already have been configured for use in another partition.
Use the IDs command on the Device submenu to correct these situations.
1. Log on as Administrator.
2. If you are not already working from a partition, select it from the View menu. Refer to Selecting a Library or Partition .
3. Select Setup—> Device—> IDs.
The Device IDs dialog box is displayed.
