AvailabilityGuard™ uses read-only XCLI commands to collect IBM XIV storage system configuration data. These commands run on one or more UNIX servers in the IT environment. Collectively, these servers can query all XIV storage systems in the scope. These servers are also known as XCLI proxies.
AvailabilityGuard™ runs read-only commands on the XCLI proxy over a secure shell (SSH) session. The connection from the proxy to the IBM XIV storage system requires authorization details (user/password) for the storage system.
AvailabilityGuard™ uses the following XCLI command syntax -
To scan an IBM XIV storage system, you should make the following preparations:
- Obtain the XCLI proxy host name or IP address.
- Obtain an OS user account for the XCLI proxy.
- Obtain the IBM storage system name or IP address.
- Obtain an IBM storage system user account with a read-only privilege.
- Verify that IP connectivity through SSH (default is port 22) is available between the
AvailabilityGuard™ collector server and each XCLI proxy.
- Verify that IP connectivity is available between the XCLI proxy and each IBM storage system that it scans.
- Avoid using the '<' and '>' characters in the password.
- In certain IBM XIV releases, a read-only user cannot run the mirror_list command. Therefore, a user with additional permissions may be required.
- In order to scan an XIV storage system, two different user accounts are required; one account for the Operating System on which XCLI is installed and a second account for the XIV storage system.
