Requirements for increasing THP V-VOL capacity

You can increase THP V-VOL capacity up to 1,182,006 cylinders.
The following requirements are important when increasing the THP V-VOL capacity:
The emulation type is 3390-A.
The THP V-VOL to be increased is not shared with the HP XP7 Storage product that does not
allow increasing the THP V-VOL (See
The THP V-VOL is not undergoing LDEV formatting.
The capacity to be added to the THP V-VOL must be specified within the range indicated
below LDEV Capacity in the Expand V-VOLs window.
The pool related to THP V-VOLs to be increased is in any one of the following statuses:
◦
Normal
◦
Exceeding the subscription limit threshold
◦
In progress of pool capacity shrinking
62 Configuring thin provisioning
Requirements
A volume whose capacity is less than 8GB (9,676 cylinders) cannot be a pool volume.
The LDEV format operation can be performed on pool-VOLs if one of these conditions is satisfied:
The THP V-VOL defined for the pool does not exist.
All THP V-VOLs defined for the pool are blocked.
Requirements
THP V-VOL (V-VOL)
The LDEV number is handled in the same way as for normal volumes.
3390-A
Up to 63,232 per pool. Any number of available THP V-VOLs can be associated with a pool.
Up to 63,232 volumes per system. If external volumes and V-VOLs are used, the total number
of external volumes and V-VOLs must be 63,232 or less.
For 3390-A, volume capacity from 1 cyl to 1,182,006 cyl per volume.
1 1.1 PB per system.
When you perform the format operation on a THP V-VOL, the storage system releases the
allocated page area in the THP V-VOL. The quick format cannot be performed. If the LDEV format
is applied to V-VOLs that are enabled for full allocation, the used capacity of the pool is not
changed before the LDEV format is applied.
