About simplified management
Independent of how an operating system is hosted, consistent storage management tools save an administrator time and reduce the complexity of the environment. Veritas InfoScale products in the guest provide the same command set, storage namespace, and environment as in a non-virtual environment.
The simplified management use case is about ease of use for provisioning virtual machines: setting up the LPARs using the same command set, storage namespace, and environment as in a non-virtual environment.
To implement simplified management use case, configure Dynamic Multi-Pathing (DMP) in the Virtual I/O server (VIOS) and implement DMP or Storage Foundation in the Virtual I/O clients or Logical partitions (LPARs).
Consistent device naming (DMP)
Provisioning virtual machines:
See About the partition migration process and simplified management.
See Provisioning data LUNs in a mixed VxVM and LVM environment.
Boot disk management: How to use DMP for the rootvg to simplify system administration and system reliability
See Using DMP to provide multi-pathing for the root volume group (rootvg).
DMP is supported in VIOS servers and in LPARs:
If DMP is installed on a VIOS server, the dmp_native_support tunable is enabled on VIOS by default. This tunable is required for DMP to work with VIOS CLIs and LVM. By default, Volume manager is disabled on VIOS.
If DMP is installed on an LPAR, the dmp_native_support tunable is disabled by default. Volume manager functionality is fully available.
If DMP in installed in both VIOS and LPAR, DMP in the LPAR displays extended attributes associated with corresponding vSCSI devices.
