Array Management Tools
Sun StorEdge 3000 family arrays use the same management interfaces and
techniques. They can be configured and monitored through any of the following
methods:
■
Using the out-of-band serial port connection (RAID only), a Solaris tip session or
terminal emulation program for other supported operating systems can be used
to access an array’s internal firmware application. All procedures can be
performed by using the firmware’s terminal interface via the COM port.
■
Using the out-of-band Ethernet port connection, a telnet session can be used to
access the firmware application. All procedures except the initial assignment of an
IP address can be done through an Ethernet port connection. Refer to the
Sun
StorEdge 3000 Family Installation, Operation and Service Manual for your array for
more information.
■
Using the out-of-band Ethernet port connection or in-band FC connection, Sun
StorEdge Configuration Service or the Sun StorEdge CLI can configure and
manage an array from a host system. Sun StorEdge Configuration Service
provides a graphical user interface (GUI) that displays information about multiple
aspects of the system at a glance. The main advantages of the CLI are that
commands can be scripted and information can be passed to other programs.
Note – To set up and use Sun StorEdge Configuration Service, refer to the Sun
StorEdge 3000 Family Configuration Service User's Guide. The Sun StorEdge CLI is
installed as part of the
SUNWsccli
package. Information about CLI functionality can
be found in the Sun StorEdge 3000 Family CLI User’s Guide , and in the
sccli
man
page once the package is installed.
SATA drives respond more slowly than FC drives when being managed by either
Sun StorEdge Configuration Service or the Sun StorEdge CLI. From a performance
standpoint, it is preferable to use these applications out-of-band to monitor and
manage a Sun StorEdge 3511 SATA array or a Sun StorEdge 3510 FC array with
attached Sun StorEdge 3511 SATA expansion units. However, security considerations
may take precedence over performance considerations.
If you assign an IP address to an array in order to manage it out-of-band, for security
reasons consider keeping the IP address on a private network rather than a publicly
routable network. Using the controller firmware to set a password for the controller
limits unauthorized access to the array. Changing the firmware’s Network Protocol
Support settings can provide further security by disabling the ability to remotely
connect to the array using individual protocols such as HTTP, HTTPS, telnet, FTP,
and SSH. Refer to the “Communication Parameters” section of the
Sun StorEdge 3000
Family RAID Firmware User’s Guide for more information.
