Figure 4-38 Change Service IP by CMM procedure
Changing the Service IP address by CLI
These addresses are not set during the installation of a Flex System V7000 Storage Node
system, but you can set these IP addresses later by using the chserviceip CLI command.
4.6 Command-Line interface (CLI)
The Flex System V7000 Storage Node command-line interface (CLI) is a collection of
commands that you can use to manage a Flex System V7000 Storage Node.
You can use the CLI to perform the following functions:
Setup of the clustered system, its nodes, and the I/O groups
Analyzing error logs (event logs)
Setup and maintenance of managed disks (MDisk) and storage pools
Setup and maintenance of client public SSH keys on the clustered system
Setup and maintenance of volumes
Setup of logical host objects
Mapping volumes to hosts
Navigating from managed hosts to volumes and MDisks, and reverse direction up chain.
Setting up and starting Copy Services:
– FlashCopy and FlashCopy consistency groups
– Synchronous Metro Mirror and Metro Mirror consistency groups
– Asynchronous Global Mirror and Global Mirror consistency groups
The CLI commands use the Secure Shell (SSH) connection between the SSH client software
on the host system and the SSH server on the Flex System V7000 Storage Node. Install and
set up SSH client software on each system that you plan to use to access the CLI.
Authenticate to the system using a password. If you require command line access without
entering a password, use an SSH public key. Then store the SSH public key for each SSH
client on the Flex System V7000 Storage Node.
