CMMVC9075E The host cluster mapping was not created because the limit of mapped volumes supported for a host in this host cluster has been reached.
Explanation
This error can occur if an attempt is made to map a new volume to a host cluster when one or more of the hosts in the host cluster already have the maximum number of mapped volumes. This error can also occur if an attempt is made to change the host cluster type to adminlun, but one of the mappings for one of the hosts in the host cluster has a SCSI LUN that exceeds the maximum for the adminlun type. The maximum number of mapped volumes for the default host type is 2048. For the adminlun host type, the maximum number of volume mappings that are not mappings to VMware vSphere Virtual Volumes is 512. Thus, the maximum SCSI LUN cannot exceed 512.
User response
Reduce the number of SCSI LUNs by using the rmvdiskhostmap command to remove at least one host mapping, then retry the command.
