When specifying
ports and WWNs
of HBAs:
Deleting SPM
names or SPM
group names
If you delete a combination of the specified port and the WWN of the
HBA from the SPM targets by using the SPM name, the SPM setting
and SPM name under the specified port are deleted. If the same SPM
name is set to another port, only the SPM setting of the specified port
is deleted.
If you delete a combination of the specified port and the WWN of the
HBA from the SPM targets by using the SPM group name, the SPM
setting and the group under the specified port are deleted. If the same
SPM group name is set to another port, only the SPM setting of the
specified port is deleted.
When specifying
ports and WWNs
of HBAs:
Resource group
function and
restrictions for
Server Priority
Manager
When you use the resource group function, the range of operation is
limited per port of resource group by Server Priority Manager. The
threshold value, the SPM name, and the SPM group name, which are
managed in the entire system, are common among the resource
groups.
When you perform Server Priority Manager operations using the
resource group function, share the threshold value that the storage
administrator determines among users of resource groups. Determine
rules for SPM names and SPM group names including port names to
avoid redundant names between ports.
