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
- 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
