• If a WWN has been updated, all host groups with the old WWN are
updated with the new one. All zones created in Storage Advisor have
the old WWN removed and new address populated.
• If a WWN is deleted, it will be removed from any host group that has
it. If the host group is left with no WWNs, the entire host group is
deleted. All zones created in Storage Advisor have the deleted WWN
removed.
• If a WWN is added, no host groups or zones are edited. You can use
Storage Advisor to add paths using the new LUN.
• Changes to name, description, IP address, or OS type do not impact
host groups.
Managing volumes
A volume is a single accessible storage area, created in a pool within a parity
group on a storage system. Create a volume and manage its properties with
Storage Advisor
About capacity saving
Capacity saving reduces the used capacity of volumes.
Storage Advisor enables you to use capacity saving when you create or
update a volume.
A capacity saving volume is a dynamically provisioned volume (DP-Vol) that
is capable of compression or both deduplication and compression.
Storage Advisor offers the following capacity saving options:
• Compression
Compression allows you to reduce the used capacity of your volume.
• Deduplication and compression
Deduplication identifies duplicate data blocks in order to remove
redundancy.
• No
No data compression or deduplication is done.
Creating volumes
Create volumes for a registered storage system so you can attach them to a
server.
When you create volumes in Storage Advisor you can:
• Create multiple volumes of the same size or different sizes at the same
time.
• Select the specific pool for volume creation or let Storage Advisor
automatically select the best pool based on utilization.
• Specify a common label and starting label suffix for identical volumes that
are the same size and have the same pool requirement.
