Recovery Manager for Oracle and Fat-to-Thin and Thin-to-Fat
To improve the existing RMO setup environment, an unlimited bidirectional conversion of volumes
from Fat-to-Thin and Thin-to-Fat is featured with HP 3PAR Operating System Software. The user
may better balance between performance and spacial optimization.
Converting Virtual Volumes
CAUTION: Due to the limitations of HP 3PAR OS, RMO is unable to retain repository information
after online Fat-to-Thin or online Thin-to-Fat conversion process. As a result, all existing Virtual
Copies, including the mounted ones, must be unmounted and removed prior to performing any
online Fat-to-Thin or Thin-to-Fat conversion. Use either the GUI or CLI (rmora_remove) to remove
all Virtual Copies. Do not use the RMO creation process during conversion. Only use the RMO
creation process when the conversion process is complete. RMO can only detect conversion on
specified volume. For example, you can still create a Virtual Copy on a datafile while a conversion
is in progress on archive log volume.
To convert database Virtual Volumes:
1.
On HP 3PAR Backup system, use the Recovery Manager GUI or command line interface to
remove all Virtual Copies of the database before converting the volumes.
2. On HP 3PAR StoreServ Storage system, enter tunevv to convert the virtual volumes.
NOTE: Please refer to HP 3PAR Operating System Software User Guide for more details
about using the tunevv command.
3. On HP 3PAR StoreServ Storage system, enter showtask to monitor the Virtual Volume
conversion completion.
