When working with SHC-OSD, it is necessary to know whether the units were generated in BS2000 or not. Usually, you work with generated units. The SHC-OSD functions are available without restriction for generated units.
With SHC-OSD you can address and administer a logical volume directly using the serial number of the storage system and the internal number of the logical volume in the storage system (internal device number). With the internal number of the logical volume each unit can be identified uniquely and independently of any server-specific names, such as different MNs on different servers for the same unit in the storage system.
This functionality is available for generated as well as for non-generated units on the local server. In the case of Symmetrix/VMAX3 this also enables units to be addressed which can only be accessed indirectly via SRDF connections. This means that it is also possible to display non-generated units and to use the control functions for local and remote replication for non-generated units.
Partitioning
Partitioning is not supported by BS2000.
With various other operating systems, it is possible to partition a logical volume and thus divide it into several independent file systems.
Problems may occur if storage volumes are operated using the serial numberand the device number because only complete logical volumes can be processed at a time.
Meta volumes
Symmetrix meta volumes are supported by BS2000.
There are no meta volumes on VMAX3.
If Symmetrix volumes are operated using the serial number and the device number, only one logical volume is processed at a time. When using meta volumes, actions are accepted only for the meta-header volume and are implicitly executed for all meta-member volumes of the meta volume. Actions on meta-member volumes are rejected with message NDE1154.
