You can shut down one site in a HyperSwap topology system
without hosts losing access to the HyperSwap volumes, if there is
an up-to-date copy of each HyperSwap volume on the site that remains
online.
Important: Host connectivity for hosts that are
connected to the site is lost when the site is shut down. You must
check that these hosts can access the nodes at the other site before
you shut down this site.
Important: Confirm that
the site that remains online has an up-to-date copy of each HyperSwap
volume, by using the management GUI.
Important: Verify that the quorum disk or the IP quorum application at site
3 is online by using the command line interface (CLI) lsquorum command.
To shut down a HyperSwap site, complete the following
steps:
- Complete the steps in Procedure: Powering off a Lenovo Storage V7000 Gen2 control enclosure.
Note: HyperSwap volumes are shown as dependent on the control
enclosure even if there is an up-to-date copy accessible from another
control enclosure.
- Optionally, power down the storage
enclosures and controllers that are providing managed disks to this
control enclosure.
