EMC Secure Remote Support Gateway for Linux Release 2.24 Operations Guide
Server Maintenance
Power sequences
EMC's customers routinely perform maintenance tasks that include
powering down and powering up their data centers based on
scheduled timeframes. While these powerdown/powerup sequences
are defined by the customers' internal processes, the presence of the
EMC Secure Remote Support Gateway in customer environments can
affect the sequence in which powerdown/powerup actions are
carried out.
IMPORTANT
!
Improper shutdown procedures generate service requests. Be sure
to notify your EMC Customer Engineer of any shutdown plans to
avoid unnecessary service calls.
Typically, the order in which powerdown sequences take place is as
follows:
1. Hosts — So that the data has a chance to destage to disk and be
captured.
2. Arrays — To allow destaging time for any pending writes to get
to the disks for storage last.
3. Networking devices — After all data has been transported to the
arrays.
4. Gateway Clients and Policy Manager servers.
IMPORTANT
!
EMC recommends that the ESRS Gateway Client server(s) and
Policy Manager servers be the last devices powered down and the
first devices powered up after maintenance is complete. This will
enable support level access to the EMC end devices at all stages in
the power up/ power down sequence.
