Creating a file system on a LUN and setting up the LUN automatically

You can create a file system on a LUN using SnapDrive for UNIX. SnapDrive for UNIX automatically create the associated LUN.

Step

  1. At the command line, enter the following command: snapdrive storage create -fs file_spec -nolvm [-fstype type] [-fsopts options] [-mntopts options] [-nopersist] -filervol long_filer_path -lunsize size [-igroup ig_name [ig_name ...]] [{-reserve | -noreserve }]
    SnapDrive for UNIX creates the file system you specify and creates a LUN for it on the storage system you specify. It performs all of the tasks associated with host preparation and discovery for the LUNs, as well as mapping and connecting the LUNs to the host entity.

Examples:

Creating a 100-MB file system directly on a LUN:
# snapdrive storage create -fs /mnt/acct1 -filervol acctfiler:/vol/vol1 -lunsize 100m -nolvm

Creating a file system on a raw LUN without any volume manager:

# snapdrive storage create -fs /mnt/vxfs2 -fstype vxfs -lun 
snoopy:/vol/vol1/lunVxvm2 -lunsize 50m -nolvm
LUN snoopy:/vol/vol1/lunVxvm2 ... created
mapping new lun(s) ... done
discovering new lun(s) ... done
LUN to device file mappings:
- snoopy:/vol/vol1/lunVxvm2 => /dev/vx/dmp/Disk_1
file system /mnt/vxfs2 created
Creating a file system on a RDM LUN without any volume manager:
# snapdrive storage create -fs /mnt/fs -fstype ext3 -lun 
lech:/vol/vol_1/lun1 -lunsize 50m -nolvm
LUN lech:/vol/vol1/lun1 ... created
exporting new lun(s) to Guest OS ... done
discovering new lun(s) ... done
LUN to device file mappings:
- lech:/vol/vol1/lun1 => /dev/sdb
file system /mnt/fs created
