impact of command “virtual-volume set-thin-enabled” on DD
Hi,
Customer wants to use command “virtual-volume set-thin-enabled” on Geosynchrony 5.5 U2 with VPLEX Metro.
All distributed devices are in production on customer environment, do you know if there is an impact on I/O or synchronization when issuing the command ?
This command is covered in the 5.5SP2 CLI Guide (https://support.emc.com/docu69395_VPLEX_Command_Reference_Guide.pdf?language=en_US&language=en_US) p.557 and I looked in the 5.5SP2 Admin Guide (https://support.emc.com/docu69393_VPLEX_Administration_Guide.pdf?language=en_US&language=en_US) p.98 “Understanding Thin Provisioning”, but there is no footnote about an impact.
Thank you for your help.
Best regards,
Cécile

I am not sure about the impact of enabling thin-enabled feature for virtual-volume on 5.5.
But here are the limitations of using thin enabled feature of Virtual-Volume: (Documented in page 36 in Release notes of 5.5)

if the virtual volume has huge IO, Changing "thin-enable" parameter affect to your host IO for 1-2 sec.
