PVSREN Renaming pubsets and volume sets

Version:

PVSREN V7.0A

PVSREN V7.0A runs on version BS2000 OSD/BC V11.0 and higher and supports SF and SM pubsets.

The utility routine PVSREN (Public Volume Sets REName) offers the following functions:

• Rename pubsets and volume sets within a notational type

• Convert one notation to another

• Create new, independent pubsets from mirror pubsets which were created using the local replication functions of external disk storage systems

Pubsets and volume sets can be renamed within a notational type or to convert one notation to another (from PUB notation to POINT notation and vice versa) without the need for reinitialization.

When renaming pubsets and converting pubset notations, there are certain restrictions that apply to the system-wide unique addressability of pubsets and the maximum length of file names.

PVSREN uses the local replication functions of external disk storage systems to create autonomous pubsets by renaming mirror pubsets. In the case of SM pubsets the renaming rules for the volume sets are stored in a parameter file. In some cases PVSREN generates the various mirror pubsets itself, in others it uses mirror pubsets created using SHC-OSD (see CREATE-PUBSET-FROM-MIRROR statement or the “SHC-OSD” manual [22 (Related publications)]).

PVSREN can also turn mirror pubsets which have already been detached and whose VSNs comply with “double-point notation” into autonomous pubsets.

In this chapter copies of pubsets which were generated using replication functions of external disk storage systems are called mirror pubsets for short.

PVSREN enables mirror pubsets which were created in double-point notation (SPECIAL-VSN) to be assigned their original names again. Renaming is possible in units of SM/SF pubsets and volume sets.

For details on the format of SF and SM pubsets see the “Introduction to System Administration” [5 (Related publications)].
