Managing Storage URIs and Shared Storage Resources

To generate and verify storage URIs or administer shared storage resources based on storage URIs, use the suriadm command.

You can use the suriadm command to verify storage URIs that were created manually, or to create storage URIs automatically, based on existing system device paths. Depending on the storage URI type, the suriadm command allows you to configure and unconfigure the corresponding storage subsystem. Given a storage URI, the same command can also identify possible instantiated device instances for the storage object described by the storage URI. The following examples demonstrate common use cases. For more information, see the suriadm(1M) man page.

Example 13  Verifying Storage URIs With the suriadm parse Syntax

The following examples show how to use the suriadm command to verify storage URIs. In these examples, the storage URI string has been parsed and its corresponding properties are displayed. Once verified, the storage URI can be used later with either the zonecfg command or the suriadm command.

root@initiator:~# suriadm parse iscsi://target/luname.naa.600144F035FF8500000050C884E50001
uri-type    iscsi
hostname    target
port        -
luname      naa.600144F035FF8500000050C884E50001

root@host:~# suriadm parse dev:/dev/dsk/c4t1d0
uri-type    dev
path        /dev/dsk/c4t1d0
Example 14  Producing Storage URIs Based on Device Path With the suriadm lookup-uri Syntax

The following example shows how to use the suriadm command to produce storage URIs. In the example, based on the existing local device path, the suriadm command output suggests valid storage URIs for later use with either the suriadm or zonecfg commands.

root@target:~# suriadm lookup-uri -t iscsi /dev/dsk/c0t600144F035FF8500000050C884E50001d0

root@host:~# suriadm lookup-uri /dev/dsk/c4t1d0

root@host:~# suriadm lookup-uri /dev/dsk/c0t600144F0DBF8AF190000510979640005d0
Example 15  Configuring iSCSI based Storage Resources With the suriadm map Syntax

The following example shows how to use the suriadm map command to configure iSCSI based storage resources. In this example, for an iSCSI storage URI, the suriadm configures the iSCSI initiator's send-targets discovery address and instantiates a local device representing the iSCSI target. The local device path from the mapped-dev storage URI property can now be used with utilities such as the zpool, format, and mkfs commands.

root@initiator:~# suriadm map iscsi://target/luname.naa.600144F035FF8500000050C884E50001
mapped-dev   /dev/dsk/c0t600144F035FF8500000050C884E50001d0s0
Example 16  Locate a Configured Storage Resource With suriadm lookup-mapping Syntax

In this example, the command is used to show the local system device currently associated with the given storage URI.

root@initiator:~# suriadm lookup-mapping iscsi://target/luname.naa.600144F035FF8500000050C884E50001
mapped-dev   /dev/dsk/c0t600144F035FF8500000050C884E50001d0s0
Example 17  Unconfigure iSCSI-Based Storage Resources With suriadm unmap

For an iSCSI storage URI, the suriadm command removes the iSCSI initiator's send-targets discovery address, and unconfigures the shared storage resource.

root@initiator:~# suriadm unmap iscsi://target/luname.naa.600144F035FF8500000050C884E50001
root@initiator:~# suriadm lookup-mapping iscsi://target/luname.naa.600144F035FF8500000050C884E50001
Failed to lookup mapping for URI: "iscsi://target/luname.naa.600144F035FF8500000050C884E50001": No such logical
