Open a Local or Remote Disk

After the library connects to a workstation or server,
VixDiskLib_Open()
opens a virtual disk. With SAN or HotAdd transport, opening a remote disk for writing requires a pre-existing snapshot.
vixError = VixDiskLib_Open(appGlobals.connection, appGlobals.diskPath, appGlobals.openFlags, &srcHandle);
The following flags modify the open instruction:
  • VIXDISKLIB_FLAG_OPEN_UNBUFFERED
    – Disable host disk caching.
  • VIXDISKLIB_FLAG_OPEN_SINGLE_LINK
    – Open the current link, not the entire chain (hosted disk only).
  • VIXDISKLIB_FLAG_OPEN_READ_ONLY
    – Open the virtual disk read-only.
As of vSphere 6.5, the following additional flags are available:
  • VIXDISKLIB_FLAG_OPEN_COMPRESSION_ZLIB
    – Open for NBDSSL transport,
    zlib
    compression.
  • VIXDISKLIB_FLAG_OPEN_COMPRESSION_FASTLZ
    – Open for NBDSSL transport,
    fastlz
    compression.
  • VIXDISKLIB_FLAG_OPEN_COMPRESSION_SKIPZ
    – Open for NBDSSL transport,
    skipz
    compression.
