Risk of damage to devices

A discharge of static electricity damages static-sensitive devices or micro circuitry.
Proper packaging and grounding techniques are necessary precautions to prevent damage.

Follow these general guidelines.

Check with a system administrator before the host computer is powered off.
For a SAS library, confirm availability or install a SAS HBA that supports multiple LUNs.
For a direct-attach Fibre Channel library, confirm availability of installation of an FC HBA.
For connection of a Fibre Channel library through a compatible switch, verify that sufficient ports are available.

Persistent binding to ensure SCSI ID assignment

When a server is booted, devices are discovered and assigned SCSI target and LUN IDs. It is possible for these SCSI assignments to change between boots. Some operating systems do not guarantee that devices are always allocated the same SCSI target ID after rebooting. Also, some software depends on this association, so you do not want it to change. The issue of SCSI ID assignment is addressed by persistent binding.
