6.2.3.2 chcluster

Shut down the Exascale cluster or modify its attributes.

Syntax

chcluster [ --attributes attribute=value[,attribute=value]... ] 
          [ --shutdown ]

Command Options

The options for the chcluster command are:

• --attributes: Specifies one or more attribute settings for the cluster.

  Use the describe chcluster command to see details about the cluster attributes you can change. See also Describing Resources and Attributes.

• --shutdown: Shuts down the Exascale cluster.

  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.
