Requirements for increasing THP V-VOL capacity
You can increase THP V-VOL capacity up to 59.9 TB. To notify the host that the THP V-VOL capacity
has been increased, make sure host mode option 40 is enabled. Processing differs as follows,
depending on the value of host mode option 40:
•
When host mode option 40 is not enabled, the host will not be notified that the THP V-VOL
capacity has been increased. Therefore, the THP V-VOL data has to be read again by your
storage system after the capacity is increased.
•
When host mode option 40 is enabled, the host is notified that the THP V-VOL capacity has
increased. If the operating system cannot recognize the value of capacity that was increased,
the THP V-VOL data has to be read again by your storage system.
The following requirements are important when increasing the THP V-VOL capacity:
•
The THP V-VOL to be increased is not shared with a P9500 product that does not allow
increasing the THP V-VOL (See
“Using Thin Provisioning and Smart Tiers with other P9500
).
•
The THP V-VOL is not undergoing LDEV formatting.
