Description
A flag affecting the COS
changes for a bitfile. By
default, when the COS of a
bitfile is changed, the BFS
copies the file to the
highest level tape storage
class in the target
hierarchy. If this flag is
ON, and if the target
hierarchy has a disk
storage class as its highest
level, the BFS will copy
the file to that disk storage
class. Otherwise, the bitfile
will be copied to the
highest tape level.
Advice: This flag should be ON when changing the COS of a file to a duplicate (2-
copies) COS. Otherwise, only the first copy of the file will be created on tape. The
second copy will not be created until the file is staged to disk, modified and then
migrated to tape.
The file name of the SFS
file where the bitfile
descriptor information is
stored.
The file name of the SFS
file where the bitfile disk
segment information is
stored.
The file name of the SFS
file where the bitfile tape
segment information is
stored.
The file name of the SFS
file where the BFS
checkpoints are stored.
The file name of the SFS
file where the bitfile disk
map information is stored.
