Exascale system components are implemented using a series of clustered software services.

To stop all of the Exascale software services in the Exascale cluster, use the ESCLI chcluster command with the --shutdown option.

However, to shut down the Exascale cluster, note that you must:

• Run ESCLI as the Exascale admin user or as another user with the cl_admin cluster level storage privilege.

• Connect ESCLI directly to an online Exascale control services (ERS) back-end server process. To do this you must start ESCLI and specify the --ctrl option as follows:

  $ escli --wallet admin-wallet-location --ctrl ERS-server-IP:8080

  To find the IP address for an online ERS server (ERS-server-IP), start a regular ESCLI session and use the following command:

  @> lsservice --filter serviceType=controlServices,status=ONLINE --attributes url

  The command displays the private IP addresses associated with all of the online ERS servers. You can use any of the reported IP addresses.

For example:

$ escli --wallet admin-wallet-location --ctrl ERS-server-IP:8080 chcluster -–shutdown
