HBA requirements

The library requires attachment to supported SAS or FC HBAs.
The library requires attachment to supported SAS or FC HBAs. See "Host connectivity" on page 27.
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.
