Manages access control records for the selected volume and its snapshots.
It is recommended that you use access control records (up to 16) to restrict host (iSCSI initiator) access to a volume and its snapshots (iSCSI targets). This will prevent multiple hosts from simultaneously accessing the same volume or snapshot and possibly corrupting data.
A volume and its snapshots share a list of access control records; however, you can specify that a record apply only to the volume, only to the volume’s snapshots, or to both. If a volume or snapshot does not have at least one access control record, no host can access it. If you do not want any host access, delete all the access control records for the volume and its snapshots.
Each access control record can restrict host access according to IP address, iSCSI initiator name, CHAP (Challenge Handshake Authentication Protocol) account name, or any combination of these methods. A host must match all the requirements specified in one record in order to access the volume or snapshot.
For testing purposes only, you can set up an access control record that allows unrestricted host access to the volume and snapshots. See the ipaddress parameter on ipaddress ip_address for more information.
