Example Example 5. The value of [Note 5] is the number of cylinders of OPEN-K/3/8/9/E CVS corresponding to the capacity specified by the SVP or the remote console. The CVS size of OPEN-K/3/8/9/E is specified by capacity in megabytes, not by the number of cylinders. The number of cylinders in an OPEN-K/3/8/9/E CVS volume can be calculated as follows (↑↑ means round up to integer): Number of cylinders = ↑(specified capacity (MB) from SVP or remote console) × 1024 / 720↑ When 37 MB is specified for OPEN-3 CVS volume from the SVP, the number of cylinders of the OPEN-3 CVS can be calculated as follows (↑↑ means round up to integer): 37 × 1024/720 = 52.62 ↑52.62↑ = 53 The OPEN-3 CVS volume has 53 cylinders. 6. The value of [Note 6] is the number of cylinders of LUSE composed of OPEN-K/ 3/8/9/E CVS volumes corresponding to the capacity specified by SVP or remote console. The CVS size of an OPEN-K/3/8/9/E device is specified by capacity in megabytes, not by the number of cylinders. To calculate the number of cylinders of OPEN-K/3/8/9/E CVS volumes (↑↑ means round up to integer): Number of cylinders = ↑ (specified capacity (MB) from the SVP or the remote console) × 1024 / 720 ↑ × n where n = the number of concatenated volumes for LUSE When an OPEN-3 CVS volume is specified as 37 MB and the volumes are concatenated, calculate the number of cylinders of the OPEN-3 CVS as follows: ↑37 × 1024/720↑ × 4 = ↑52.62↑ × 4 = 53 × 4 = 212 The LUSE for OPEN-3 CVS volume has 212 cylinders. 56 hp surestore disk array xp operating system configuration guide: SGI IRIX
