Table 15. HPC iSCSI Provider Settings (continued)
Setting Default Value Description
storage reaches the warning level, the PS Series group will
issue an alert. When the assigned storage reaches the
maximum value, no further storage can be assigned to the
volume. For base volumes, the minimum volume reserve
cannot be less than 10 percent.
Difference Volume Provisioning 0%, 80%, 100% These parameters have the same effect as the base volume
provisioning parameters, but apply to differencing volumes.
Create new volumes with open ACLs no Normally the HPC server maps a volume to a given node,
which causes an ACL to be set on the volume. In some cases
this might cause problems, particularly if the HBA is not using
the IQN string the HPC Server has assigned to it during boot.
Selecting this option will cause all volumes created by the
iSCSI Provider to be assigned an unrestricted ACL, meaning
that any initiator will be able to connect. You should only
enable this option if you are experiencing authorization failures
when nodes attempt to log in to their assigned volumes.
