Avaya Application Server - Expand Disk Space

[dsm600rr]

Hello all,

I am deploying a R11.1 .ova Backup Application Server via VMware Workstation.

I have installed the .ova however it did not let me specify the system settings prior to installing.

It installed with a default 100GB Disk Space.

In VMware Workstation, I expanded it to 300GB:

After that was done, I got the message:

Anyone know how to complete this? Thank you.

Figured it out, if anyone is curious:

Not needed any more, but I use the following script for this:

#!/bin/bash
##########
# Script to resize a LVM Partition after extending the underlying disk device. Can be used on physical or virtual machines alike.
# Tested with CentOS6, RHEL6, CentOS7, RHEL7. This script is only intended for MBR partitioned disks and not for GPT.
#
# The script will first resize the partition by changing the partition end sector of the selected partition, and then after a reboot resize the filesystem.
# By default it rescans the SCSI bus to check a change in disk size if the disk was hot-extended, which is easy with VMs, and only then proceeds.
# If the extended disk size is recognized by the OS already, you can force resizing with the -f flag.

usage() {
  echo "Usage:
$0 [-p <LVM physical volume>] [-l <LVM logical volume>] [-f]
 
Options:
 -p physical LVM volume device to extend (check pvdisplay)
 -l logical LVM volume to extend (check lvdisplay)
 -f force extending without a disk rescan. Use this if the OS has detected the enlarged disk already, otherwise we first check whether the underlying disk is larger after a SCSI rescan
    
Example:
./lvmresize.sh -p /dev/sda2 -l /dev/VolGroup/lv_root -f
 
It is highly recommended you backup the boot sector of your disk before as a safety measure with something like the following:
# dd if=/dev/sda of=sda_mbr_backup.mbr bs=512 count=1 
# sfdisk -d /dev/sda > sda_mbr_backup.bak
 
You can restore the partition table then like this:
# dd if=sda_mbr_backup.mbr of=/dev/sda bs=512 count=1
# sfdisk /dev/sda < sda_mbr_backup.bak --force" 1>&2
  exit 1
}
