The Question is:
How can I resize disk volume size without loosing data on it ? We have an EVA
storage, and when I change it's size "on-the-fly", I'd like to see that on
system (after INITIALIZE show device /size ... show it is bigger) without
loosing data on the disk.
The Answer is :
To enable Dynamic Volume Expansion (DVE) on an existing disk volume
(available on V7.3-2 and later), dismount the volume and remount it
privately. Issue the DCL command SET VOLUME/LIMIT. Dismount and
then remount the volume appropriately; remount the volume for your
normal operations. When more storage is required, you can now
issue the DCL command SET VOLUME/SIZE to resize the volume.
