How to increase the provisioned size of a volume in Pure Flash Array storage using CLI

In a "storage administrator" profession, it is quite common to receive requests for space
expansion/increase on SAN volumes. Pure Flash Array has both CLI and GUI options available to increase provisioned space of a storage volume. in this article, we will be exploring the possible CLI options for the same. 

The purevol setattr --size command increases the allocated size of a volume. The attribute changes will be visible by the host immediately. 

Commonly used options are:

                VOL                   volume name

              --size SIZE           new virtual size as perceived by hosts

syntax: purevol setattr --size SIZE  VOL 

The following example creates a volume named PRODVOL01 with an initial size of 10G

pureuser@flasharray1> purevol create --size 10G PRODVOL01

Name       Size  Source  Created                  Serial

PRODVOL01  10G   -       2021-12-16 07:49:44 PST  66C228E8DB224F9D000113FB

In the following example, we have used purevol seattr command to increase the virtual size of the storage volume. 

pureuser@flasharray1> purevol setattr --size 15G PRODVOL01

Name       Size

PRODVOL01  15G
