The example given in Figure  4-1 has a raidsize of four. If applicable, specify a spare disk for the MDS volume. Disk sparing is an optional feature that allows data from a failed disk to be rebuilt to a spare without interrupting your OVS service. You need to run mdsvstat to obtain the proper volume bandwidth, maxbw parameter, in order to use the volume as a real-time volume. If the volume specification is correct, continue with the installation.
Streams Specify the number of video streams for the first video pump.
Ensure that your hardware configuration can support the number of video streams specified. Initializing the Oracle Media Data Store You may choose to have the Oracle Installer initialize the MDS volume for you. Before you can operate OVS, the MDS must be initialized. This process writes information from the voltab file created by the Oracle Installer to each of the disks in the MDS volume. The disks to be initialized are free of any necessary data or have been appropriately backed up.
