Enclosure ID Settings:
˙
The configurable IDs start from 1 to 6. Usually the numbering
starts from the one closest to the managing RAID enclosure.
˙
The subsystem can connect to a maximum of six (6) JBODs.
˙
Make sure a unique ID is configured on each JBOD so that the
SAS WWN addresses of disk drives can be properly assigned.
RAID system firmware automatically manages these addresses.
