NAME

       gluPartialDisk - draw an arc of a disk

C SPECIFICATION

       void gluPartialDisk( GLUquadric* quad,
			    GLdouble inner,
			    GLdouble outer,
			    GLint slices,
			    GLint loops,
			    GLdouble start,
			    GLdouble sweep )

PARAMETERS

       quad    Specifies a quadrics object (created with gluNewQuadric).

       inner   Specifies the inner radius of the partial disk (can be 0).

       outer   Specifies the outer radius of the partial disk.

       slices  Specifies the number of subdivisions around the z axis.

       loops   Specifies the number of concentric rings about the origin into which the partial disk is subdivided.

       start   Specifies the starting angle, in degrees, of the disk portion.

       sweep   Specifies the sweep angle, in degrees, of the disk portion.

DESCRIPTION

       gluPartialDisk  renders	a partial disk on the z=0 plane. A partial disk is similar to a full disk, except that only the subset of the disk
       from start through start + sweep is included (where 0 degrees is along the +yaxis, 90 degrees along the +x axis, 180 degrees along  the	-y
       axis, and 270 degrees along the -x axis).

       The partial disk has a radius of outer, and contains a concentric circular hole with a radius of inner. If inner is 0, then no hole is gen-
       erated. The partial disk is subdivided around the z axis into slices (like pizza slices), and also about the z axis into rings  (as  speci-
       fied by slices and loops, respectively).

       With  respect  to orientation, the +z side of the partial disk is considered to be outside (see gluQuadricOrientation).	This means that if
       the orientation is set to GLU_OUTSIDE, then any normals generated point along the +z axis. Otherwise, they point along the -z axis.

       If texturing is turned on (with gluQuadricTexture), texture coordinates are generated linearly such that where r=outer, the value at (r, 0,
       0) is (1.0, 0.5), at (0, r, 0) it is (0.5, 1.0), at (-r, 0, 0) it is (0.0, 0.5), and at (0, -r, 0) it is (0.5, 0.0).

NAME

       volrootmir - Mirror areas necessary for booting to a new disk

SYNOPSIS

       /usr/sbin/volrootmir [-a] [nconfig=count] target_disk [swap=target_partition]

OPTIONS

       Specifies that all volumes on the system disk be mirrored, not just the root and swap volumes, rootvol and swapvol.

DESCRIPTION

       The volrootmir script causes a mirror copy of areas of the root disk involved in booting to be made on the specified target disk.

       When  used without the -a option, volrootmir adds mirrors of the root and swap volumes and allocates them on the new disk. In addition, all
       disk regions required for booting are set up and partitions for the new volume mirrors are created.

       When used with the -a option, volrootmir mirrors all in-use partitions on the system disk.

       To mirror a swap volume that is on a separate disk from the root volume, the swap attribute must be used to specify a separate  target  for
       the swap mirror.

       The  target  disk(s)  must be at least as large as the sum of the sizes of rootvol and swapvol. Also, the physical disk should not have any
       disk partition in use.

       This script can be called from the voldiskadm menus by choosing the Mirror volumes on a disk operation.

ATTRIBUTES

       Specifies the number of log copies and copies of the configuration database, for example,  nconfig=2.   Specifies  that	the  swap  volume,
       swapvol, be mirrored on a separate disk, as specified by target_partition.

EXAMPLES

       The following command mirrors the rootvol and swapvol volumes onto the target disk, dsk3. This command will fail if swapvol is on a differ-
       ent disk from rootvol.

	      # volrootmir dsk3 The following command mirrors rootvol, swapvol, and any other volumes on the root disk onto the target disk, dsk3.
	      This command will fail if swapvol is on a different disk from rootvol.

	      #  volrootmir -a dsk3 The following command mirrors rootvol on disk dsk3, swapvol onto partition dsk7d, and any other volumes on the
	      root disk onto disk dsk3. This command will fail if swapvol is on the same disk as rootvol.

	      # volrootmir -a dsk3 swap=dsk7d The following command mirrors rootvol onto disk dsk3 and swapvol onto partition dsk7d. This  command
	      will fail if swapvol is on the same disk as rootvol.

	      # volrootmir dsk3 swap=dsk7d
