Creating an LVM entity and specifying the LUN

You can create a host entity such as a file system, logical volume, or disk group and specify the LUN that is created as part of it.

Step

  1. At the command line, enter the following command: snapdrive storage create -host_lvm_fspec -lun long_lun_name [lun_name...] -lunsize size [-igroup ig_name [ig_name...]] [{ -reserve | -noreserve }]
    Example
    This example creates the file system /mnt/acctfs with file system depending on your host. It sets up three LUNs on the storage system acctfiler. Each LUN is 10 GB:# snapdrive storage create -fs /mnt/acctfs -fstype jfs2 -lun acctfiler:/vol/vol1/lunA lunB lunC -lunsize 10g
    LUN acctfiler:/vol/vol1/lunA ... created
    LUN acctfiler:/vol/vol1/lunB ... created
    LUN acctfiler:/vol/vol1/lunC ... created
    mapping new lun(s) ... done
    discovering new lun(s) ... done
    LUN to device file mappings:
    - acctfiler:/vol/vol1/lunA => hdisk2
    - acctfiler:/vol/vol1/lunB => hdisk3
    - acctfiler:/vol/vol1/lunC => hdisk4
    disk group acctfs_SdDg created
    host volume acctfs_SdHv created
    file system /mnt/acctfs created
    LUN acctfiler:/vol/vol1/lunA ... created
    LUN acctfiler:/vol/vol1/lunB ... created
    LUN acctfiler:/vol/vol1/lunC ... created
    mapping new lun(s) ... done
    discovering new lun(s) ... done
    LUN to device file mappings:
    - acctfiler:/vol/vol1/lunA => /dev/vx/rdmp/c4t0d3s2
    - acctfiler:/vol/vol1/lunB => /dev/vx/rdmp/c4t0d7s2
    - acctfiler:/vol/vol1/lunC => /dev/vx/rdmp/c4t0d8s2
    disk group acctfsvg created
    host volume acctfshv created
    file system /mnt/acctfs created
