ADD FILESET Command
STOPPED
No attempt is made to start the fileset when a system load occurs. No attempt 
is made to start the fileset during a restart of the OSS environment, unless the 
fileset has been manually started.
This is the default value.
DEVICELABEL devicelabel
specifies the device label assigned to this fileset. The specified label must not 
already be in use by another fileset in the database. The device label has 6 
characters (the first of which is always zero) and consists of numeric characters 
(0 - 9) and uppercase letters (A - Z), excluding E, I, O, and U. The root fileset 
always has a device label of 000000. Valid device labels are in the range 000001 
through 0ZZZZZ. The default value for DEVICELABEL is the lowest unused device 
label in the database.
FSCKCPU processor
specifies the processor number of the processor that should run the FSCK 
program when a fileset recovery is automatically initiated, where processor is in 
the range 0 through 15 or is -1. The value -1 indicates that the processor that runs 
the primary copy of DP2 for the fileset catalog should be used.
If the processor indicated by a nonnegative processor value is not available, 
then the processor specified for the SUBSYS FSCKCPU option is used. If that 
processor is also unavailable, the processor in which the OSS Monitor is running is 
used.
If an FSCKCPU option is omitted from the FILESET configuration, then the 
processor specified for the SUBSYS FSCKCPU option is used when a fileset 
recovery is automatically started.
FTIOMODE { UNBUFFEREDCP | DP2BUFFEREDCP | OSSBUFFEREDCP }
specifies the input/output buffering and fault tolerance for application file opens that 
use the O_SYNC option:
UNBUFFEREDCP Use unbuffered input/output with checkpointing. This 
behavior provides maximum fault tolerance but with 
reduced performance.
DP2BUFFEREDCP Use disk-process-buffered input/output with 
checkpointing. This behavior provides fault tolerance for 
single failures, with better performance than 
UNBUFFEREDCP. DP2 buffers file data and checkpoints 
the file state to its backup process to ensure recovery 
from single failures.
