Note – If you reset the controller during a telnet session, you are disconnected from
the RAID array. Use the
telnet
command to log back in to the array.
6. To connect the Sun StorEdge Configuration Service program (on a host server) to a
RAID array that has an IP address, refer to the out-of-band management
instructions in the
Sun StorEdge 3000 Family Configuration Service User’s Guide.
The same document’s “Email and SNMP” appendix provides information about
configuring Sun StorEdge Configuration Service software to use Simple Network
Management Protocol (SNMP) traps and Management Information Bases (MIBs) to
provide information to other out-of-band enterprise management software. The
“Monitoring the Array” chapter explains the use of Sun StorEdge Configuration
Service agents to redirect event messages into host system logs.
4.10 Cabling to Expansion Units
FIGURE 4-12
shows an example of a RAID array connected to two expansion units.
You can connect up to eight expansion units to a RAID array in certain
configurations. These configurations are described in the
Sun StorEdge 3000 Family
Best Practices Manual .
The connections to the expansion units are designed to keep all A drive ports on the
same loop and all B drive ports on the same loop. Several cabling configurations are
possible, each with its own advantages and disadvantages. Refer to the
Sun StorEdge
3000 Family Best Practices Manual for the Sun StorEdge 3510 FC array for more
information about the suitability of various configurations for various application
requirements, as well as for information about configurations involving more than
two expansion units.
