Chapter 4 Configuring Your Library
Configuring Devices
Scalar i2000 User’s Guide 148
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.
Device IDs 4
From a partition, you can change the SCSI ID for a SCSI-attached drive or
the Loop ID for a Fibre-attached drive. For example, the default SCSI ID
for a drive that you are installing might conflict with the assigned SCSI ID
of an existing drive. You might be using an application that expects to
communicate with a device at a specific SCSI ID, but that ID might
already have been configured for use in another partition. Use the
Setup→ Device→ IDs command to correct these situations.
1 Log on as an administrator.
2 Make sure that you are viewing the partition that includes the drive
you want to configure. From the View menu, click the name of the
appropriate partition.
3 Click Setup→ Device→ IDs.
The Device IDs dialog box appears. (The following two examples show
the SCSI version of the Device IDs dialog box, and then the FC version.)
