7.2.11 Interconnect Assembly
Note – Rackmounted disk arrays must be removed from a cabinet before replacing
an interconnect assembly. See Section 7.2.12 “Removing a Rackmounted Disk Array”
on page 7-26 for removal instructions.
Caution –
The interconnect assembly is not a hot-plug item. You must remove
power to the disk array before replacing the interconnect assembly.
The disk array interconnect assembly contains the world wide number (WWN) of
the disk array. The WWN is used by the SCSI Enclosure Services (SES) software to
communicate with the disk array and obtain enclosure and environmental status. If
the interconnect assembly is replaced, the WWN will change and SES will no longer
see the disk array. Therefore, the
luxadm
command must be used to update the
software.
