NAME

rvdexch − exchange names of two Remote Virtual Disk (RVD) packs

SYNOPSIS

/usr/ibm/rvdexch [ −d ] server pack1 uid1 pack2 uid2

DESCRIPTION

Rvdexch exchanges the names of two RVD packs on a server host server. It will prompt for exclusive-mode passwords of each pack, and then send a name exchange request to the RVD server.  The −d flag enables debugging.  Pack1 and pack2 are names of packs and must be presently associated with the two packs.  Uid1 and uid2 are unique identifiers of the packs as given in /etc/rvd/rvddb. 

Note: The nature of the change instilled by rvdexch is ephemeral in that it exists only on the running server, and will disappear when the server is next restarted. 

BUGS

The current control protocol provides no fail-safe mechanism in the event of a lost acknowledgement from the server.  Should this happen, another request would be sent, undoing the effects of the previous one.  This may be circumvented by running rvdexch on the server machine, thereby eliminating the possibility of a lost acknowledgement.
