§LibStorageMgmt

LibStorageMgmt provides a set of API for programmatically manage their storage hardware in a vendor neutral way supporting these actions:

  • List storage pools, volumes, access groups, or file systems.

  • Create and delete volumes, access groups, file systems, or NFS exports.

  • Grant and remove access to volumes, access groups, or initiators.

  • Replicate volumes with snapshots, clones, and copies.

  • Create and delete access groups and edit members of a group.

  • List Linux local SCSI/ATA/NVMe disks.

  • Control IDENT/FAULT LED of local disks via SES(SCSI Enclosure Service), NPEM, VMD (utilizes ledmon library)

To use LibStorageMgmt rust binding, you need:

§Example code using simulator plugin

extern crate lsm;
use lsm::{Client, LsmError};

    let mut c: Client = match Client::new("sim://", None, None) {
        Ok(i) => i,
        Err(e) => {
            match e {
                // Error handling goes here
                LsmError::DaemonNotRunning(_) =>
                    panic!("Please start the libstoragemgmt daemon"),
                _ => panic!("{}", e)
            };
        },
    };
    let syss = match c.systems() {
        Ok(i) => i,
        Err(e) => panic!("{}", e)         // Please use error handling as above.
    };
    for s in syss {
        let cap = match c.capabilities(&s) {
            Ok(i) => i,
            Err(e) => panic!("{}", e)     // Please use error handling as above.
        };
        if cap.is_supported(lsm::Capability::Volumes) {
            let vols = match c.volumes() {
                Ok(i) => i,
                Err(e) => panic!("{}", e) // Please use error handling as above.
            };
            for vol in vols {
                println!("Got volume: {} {}", vol.name, vol.id);
            }
        }
    }

Modules§

Structs§

  • Access group is also known as host group on some storage system, it defines a group of initiators sharing the same access to the volume.
  • Represent a battery.
  • Represent a block range used Client::volume_replicate_range().
  • Represent capabilities supported by specific system.
  • Represent the connection to plugin.
  • Represent NFS access control information.
  • Represent a plugin information
  • Represent pool membership information.
  • Represent a storage system. Examples:
  • Represent a target port which is the front-end port of storage system which storage user/client connect to and get storage service from.
  • Represent a storage volume. Also known as LUN(Logical Unit Number) or Storage Volume or Virtual Disk. The host OS treats it as block devices (one volume can be exposed as many disks when multipath I/O is enabled).
  • Represent volume cache information.
  • Represent volume RAID information.
