5.3.1 Upgrading Controller Firmware
When upgrading controller firmware, make sure there are no additional telnet or
FTP sessions to the Sun StorEdge T3 disk tray. Halt all disk tray activity (no I/Os
running from the host), and keep activity through the one remaining telnet session
to a minimum. Also, be sure the system is in an optimal state before starting the
upgrade by verifying the system controller states:
■
Use the
port listmap
command to verify that no failover conditions have
occurred.
■
Use the
vol stat
command to verify that all disk drives in the partner group are
optimal.
Refer to the Sun StorEdge T3 Disk Tray Administrator’s Guide for more information on
these commands.
