5 Basic operation
Powering on/powering off
Before powering on the enclosure for the first time:
• Install all hard drives in the enclosure so that the connected host controller can identify and configure
them at power-up.
• Connect the cables and power cords to the enclosure as explained in the Installation Poster.
• Generally when powering up, make sure to power up the enclosures and associated data host in the
following order:
•Drive enclosures first
• Controller enclosure next
• Data hosts last (if they are powered down for maintenance purposes)
To power on the system:
1. Press the power switches at the back of each drive enclosure to the On position.
2. Press the power switches at the back of the controller enclosure to the On position.
To power off the system:
1. Stop all I/O from hosts to the system.
2. Use SMU to shut down both controllers. See the SMU online help or CLI reference guide for information
on shutting down controller.s
Wait until SMU indicates that processing is complete.
3. Press the power switches at the back of the controller enclosure to the Off position.
4. Press the power switches at the back of each drive enclosure to the Off position.
Updating firmware
After installing the hardware and powering up the enclosure for the first time, be sure to verify that the
controllers and drive enclosures have the latest firmware. SMU enables you to view the software, hardware,
and other version information for each controller and the enclosures.
To view controller version information, in the Configuration View panel, right-click the system, select View >
Overview, and select the Versions button in the System Overview Table. To view drive enclosure
information, in the Configuration View panel, right-click the enclosure and select View > Overview. The
enclosure firmware is listed as EMP A Revision and EMP B Revision.

Selecting an appropriate time to perform the online upgrade
To ensure the success of an online upgrade, selecting the appropriate time is essential. Selecting a period
of low I/O activity will ensure the upgrade completes as quickly as possible, and will avoid disruptions to
host and applications due to timeouts. Attempting to upgrade a storage system that is in the middle of
processing a large I/O intensive batch job will likely cause hosts to lose connectivity with the storage
system. Consequently, finding an appropriate time for the upgrade is very important.
