HPE StoreVirtual 3200

Adding storage system capacity
The capacity of the storage system can be increased by adding disk drives to an existing enclosure, or by
adding another HPE StoreVirtual 3200 drive enclosure. Up to three drive enclosures can be added to the
storage system for a total of four enclosures.
IMPORTANT:
Removing existing disk drives or an existing drive enclosure from the storage system to reduce
usable capacity is not supported.
Default RAID settings by drive type
• LFF drives default to RAID 6 but can be configured with RAID 10. RAID 5 is not allowed.
• SSD drives default to RAID 5 but RAID 10 and RAID 6 can be configured
• SFF HDDs default to RAID 6 but RAID 5 and RAID 10 can be configured.
If there are not a sufficient number of drives to configure a default RAID mode of RAID 5 or RAID 6, then
RAID 10 will be used since it requires fewer drives.
NOTE:
Hewlett Packard Enterprise recommends tier 1 (15K SAS, 10K SAS) drives, which default to RAID
6. To avoid mixed RAID groups, you might have to change the default from RAID 6 to RAID 5.
End-to-end process for adding drives and drive
enclosures
Adding disk drives and drive enclosures
NOTE: Depending upon the configuration, set aside an hour to add disk drives and drive
enclosures.
Procedure
1. Stop all applications that are using the StoreVirtual storage system.
2. Stop all disk I/O to and from the StoreVirtual storage system.
3. Unplug both power supplies from the StoreVirtual storage system.
4. Install all disk drives in the new enclosure.
See Adding disk drives for more information.
5. Mount the drive enclosure.
See Adding a disk enclosure for more information.
6. Connect the SAS cables from new enclosure to the StoreVirtual storage system.
See Network cabling configurations for more information.
7. Apply power to the new enclosure and wait one minute.
8. Apply power to the StoreVirtual storage system.
