Installing a CX200-Series DPE2
CAUTION
!
The drives read their FC-AL physical address only at powerup or
when the drive is reset. To avoid potential data loss, you must set
the enclosure address when you install the disk enclosure and
power is off; you cannot change the EA while power is on.
For instructions on how to initialize your system after its first
powerup, refer to the EMC Storage Systems CX200-Series Initialization
Guide and the EMC Installation Roadmap for CX-Series and FC-Series
Storage Systems.
CX200-Series Powerdown
If a CX200 with an SPS is powered down abnormally (for example, a
brownout or ac failure), cached data is saved to the storage-system
vault disks. However, when the CX200 is powered back up again, it
may take longer to come on line.
Turning Off the
Power
1. Stop all I/O activity to the DPE2.
Stopping the I/O allows the SP in a CX200 DPE2 to transfer cache data,
and may take some time. The length of time will be based on criteria such
as the amount of cache, the amount of data in the cache, the type of data
in the cache, and the target location on the disks, but it is typically less
than one minute. CX200LC systems do not support write-caching.
2. If the server connected to the CX200/CX200LC is running the
UNIX® operating system, unmount file systems.
3. Use the power switch on an SPS to turn off power to the CX200
DPE2 and any other device connected to the SPS. If the
power/cooling module is not connected to an SPS, turn off power
with the power/cooling module power switch. See Figure 2-11.
