• When deleting the Affinity Group during operation, stop access from th e
host that assigns the Affinity Group by the [Allocate Host-Affinity Group]
function.
To delete Affinity Groups during operation, it is necessary to delete the
Host-Affinity Group settings of the Affinity Groups to be deleted using
the [Allocate Host-Affinity Group] function in advance.
• When changing an in use Affinity Group, host access should be handled
as follows:
- Host access should be stopped when changing or deleting a Logical
Volume used by an in use Affinity Group. Use the [Allocate Host-
Affinity Group] function.
- Host access does not need to be stopped when adding a new
Logical Volume to an in use Affinity Group.
• Host access does not need to be stopped when adding a new Affinity
Group.
• The Host-Affinity function can be used if the [Affi n i t y M o d e ] o f t h e t a r g e t
FC-CA Port or iSCSI-CA Port is [ON (Enabled)].
