vxenablef(1M) vxenablef(1M) NAME
vxenablef - enable VxFS DMAPI, OnLineJFS, or full VxFS functionality in the kernel SYNOPSIS
DESCRIPTION
enables VxFS DMAPI (Data Management Applications Programming Interface), OnLineJFS functionality, or full VxFS functionality in the kernel. If you have valid licenses for these features, makes them available without rebuilding a new kernel and rebooting the system. If no argument is specified, displays the available licensed features enabled in the kernel. Options recognizes the following options. Enable all features for which the proper license key exists. Scans for license keys for HP-installed products such as HP_OnLineJFS and products dependent on DMAPI (Data Manage- ment Applications Programming Interface) and enables them. You need not specify the option if you specified the option. Enable DMAPI, full VxFS, or OnLineJFS features. enables DMAPI functionality in the kernel if the system is licensed for DMAPI. DMAPI is also part of the HP OnLineJFS product, but this option enables DMAPI without OnLineJFS. enables all features, including VERITAS Quick I/O, if the features are licensed with a valid VERITAS license key. This option is not available for HP-UX/HP_OnLineJFS users. enables OnLineJFS functionality in the kernel if the system is licensed for OnLineJFS. The HP OnLineJFS product includes DMAPI. Notes is run automatically from at system boot time. It is also run during the installation of the HP OnLineJFS product to enable the newly- licensed OnLineJFS functions without requiring a system reboot. It is not typically run from the command line. You must be a privileged user to run SEE ALSO

xfs_bmap(8) System Manager's Manual xfs_bmap(8) NAME
xfs_bmap - print block mapping for an XFS file SYNOPSIS
xfs_bmap [ -adlpv ] [ -n num_extents ] file DESCRIPTION
xfs_bmap prints the map of disk blocks used by files in an XFS filesystem. The map lists each extent used by the file, as well as regions in the file that do not have any corresponding blocks (holes). Each line of the listings takes the following form: extent: [startoffset..endoffset]: startblock..endblock Holes are marked by replacing the startblock..endblock with hole. All the file offsets and disk blocks are in units of 512-byte blocks, no matter what the filesystem's block size is. OPTIONS
-a If this option is specified, information about the file's attribute fork is printed instead of the default data fork. -d If portions of the file have been migrated offline by a DMAPI application, a DMAPI read event will be generated to bring those por- tions back online before the disk block map is printed. However if the -d option is used, no DMAPI read event will be generated for a DMAPI file and offline portions will be reported as holes. -l If this option is used, then <nblocks> blocks will be appended to each line. nblocks is the length of the extent described on the line in units of 512-byte blocks. This flag has no effect if the -v option is used. -n num_extents If this option is given, xfs_bmap obtains the extent list of the file in groups of num_extents extents. In the absence of -n, xfs_bmap queries the system for the number of extents in the file and uses that value to compute the group size. -p If this option is used, xfs_bmap obtains all unwritten (preallocated) extents that do not contain written data. With the -v option, the flags column will show which extents are preallocated/unwritten. -v Shows verbose information. When this flag is specified, additional AG specific information is appended to each line in the following form: agno (startagoffset..endagoffset) nblocks flags A second -v option will print out the flags legend.
