VxVM vxresize ERROR V-5-1-4703 Problem running vxassist command for volume , in diskgroup

# vxassist -g maxgrow
VxVM vxassist ERROR V-5-1-15319 Volume cannot be extended within the given constraints: Not enough HDD devices that meet specifications.

 The volume configured under FSS kept some rules on that particular volume.

Confirm by using the below command.

# vxassist -g listrule
volume rule {
mirror=host <<<< This mirror=host looking for exported/remote luns
require=array:internal
}

Check that volume is no longer an FSS volume.

1. List the rules for that particular volume.
# vxassist -g listrule

2. Clear the rules so that you can extend the volume as a normal volume.
# vxassist -g clearrule

3. Retry vxresize or vxassist
# vxassist -g maxgrow
