VAS is a QUEST (formerly DELL) software that allows validating GAD account in Unix environments.
If running vastool status you receive an error of no srvinfo, then first check DNS entries in resolv.conf to assure the servers are correct and that also resolve hosts
root@server1:/root# /opt/quest/bin/vastool status
Host: <server1, SunOS 5.10 sparc>
Date: <Tuesday, 22 November 2016 15:58:18 CET>

Check current UUID blkid values:
root@datadroid:~# blkid|grep sda2 /dev/sda2: LABEL="omv" UUID="a4b494db-320a-4ce2-bb3a-841db943f9c0" TYPE="ext4" PARTUUID="000ddd31-02"
To update or modify the UUID run tune2fs
root@datadroid:~# tune2fs /dev/sda2 -U 804a6f55-0432-491b-9a97-65cff6571f3d
Check again root@datadroid:~# blkid|grep sda2 /dev/sda2: LABEL="omv" UUID="804a6f55-0432-491b-9a97-65cff6571f3d" TYPE="ext4" PARTUUID="000ddd31-02"
Deadline Scheduler
The deadline algorithm attempts to limit the maximum latency and keep the humans happy. Every I/O request is assigned its own deadline and it should be completed before that timer expires.

Reasons to use the deadline scheduler include:

after adding the OVPN configuration file and the p12 key in the iPhone, we will receive an error and the connection is not successfull. In order to solve this we need to add in the ovpn configuration file between <ca> </ca> the root certificate of the OpenVPN server.
For example:
#OpenVPN Server conf
tls-client
client
dev tun
proto tcp
tun-mtu 1400
nobind
remote server.example.com 1194
pkcs12 iphone.p12
cipher BF-CBC
verb 3
ns-cert-type server
<ca>
