IBM DS6000 / DS8000 Scan Requirements

AvailabilityGuard uses read-only DSCLI commands to collect configuration data from IBM DS6000 and DS8000 storage systems. These commands run on one or more UNIX servers in the IT environment. Collectively, these servers can query all DS arrays in the scope. These servers are also known as DSCLI proxies.

AvailabilityGuard runs read-only commands on the DSCLI proxy over a secure shell (SSH) session. The connection from the proxy to the IBM DS storage system requires authorization details (user/password) for the storage system.

AvailabilityGuard uses the following DSCLI command syntax:
dscli -hmc1 <array IP/name> -user <user> -passwd <passwd> <command>

To scan an IBM DS6000/8000 storage system, you should make the following preparations:

• Obtain the DSCLI proxy host name or IP address.
• Obtain an OS user account for the DSCLI proxy.
• Obtain the IBM storage system name or IP address.
• Obtain an IBM storage system user account .
• Verify that IP connectivity through SSH (default is port 22) is available between the AvailabilityGuard collector server and each DSCLI proxy.
• Verify that IP connectivity is available between the DSCLI proxy and each IBM storage system that it scans.

Note: In order to scan an IBM DS storage system, two different user accounts are required; one account for the Operating System on which DSCLI is installed and a second account for the IBM DS storage system.
