IT25117: IBM SPECTRUM PROTECT PLUS DOCUMENTATION MISSING DETAILS ON VSNAPDISK MANAGEMENT

Download Information: Version 10.1.2.x IBM Spectrum Protectâ„¢ Plus

APAR status

• Closed as documentation error.

Error description

• IBM Spectrum Protect Plus documentation does not make any
  mention of disk provisioning for vSnap storage. The
  documentation should state that thick provisioning is
  recommended for accurate views of available space.  Using thin
  provisioned disks limits Spectrum Protect Plus from identifying
  a lack of space within the datastore that prevents the expansion
  of the vSnap storage pool.
  
  The documentation does not make references on how to manage the
  removal of existing vSnap storage volumes which cannot be used,
  for example if they were created with the wrong provisioning.
  The documentation should provide guidance on how to correctly
  manage the vSnap storage volumes in situations where it is
  necessary to remove them.
  
  Versions Affected: IBM Spectrum Protect Plus 10.1.0, 10.1.1

Problem conclusion

• The IBM Spectrum Protect Plus User's Guide and Knowledge
  Center were enhanced to include (a) the requirement that
  disks attached to vSnap must be thick provisioned;
  and (b) a statement that once a disk has been added to a
  raid0 pool it cannot be removed; disconnecting the disk
  will result in the pool becoming unavailable and the only
  solution is to destroy and recreate the pool.
