Table 1-30: Sync and Syncd Subcommand Parameters (Continued)
Parameter
Argument all: Synchronizes all logical devices. The logical device on which the CCI
(continued) software is installed and the logical device containing the Windows 2000
or Windows Server directory is excluded.
If a directory-mounted volume exists in the specified logical device, the
data will be flushed including the directory-mounted volume as follows:
pairsplit –x sync all
[SYNC] C: HarddiskVolume1
[SYNC] D: \hd1 HarddiskVolume8
[SYNC] D: \hd2 HarddiskVolume9
[SYNC] G: HarddiskVolume10
drive#(0-N) ...: Specifies the range of devices on the Windows 2000 or
Windows Server system.
Volume#(0-N) ...: Synchronizes the data to the specified LDM (logical
device manager) volume.
The LDM volume specifies the following device objects: \Vol#, \Dms#,
\Dmt#, \Dmr#, or Volume{GUID}.
Note The sync command executes the following procedures depending on the
execution condition.
If the logical device is closed from the application, the system buffer is
flushed and changes the logical device to "Dismount" status.
If the logical device is opened from the application, the sync option flushes
the system buffer only. In this case, [WARNING] will be displayed.
pairsplit –x sync –C:
WARNING: Only flushed to [\\.\C] drive due to be opening.
[SYNC] C: HarddiskVolume3
If the logical drives designated as the objects of the sync command will not
be opened to any applications, then the syncd command flushes the
system buffer to a drive and holds the delayed (paging) I/O (30 sec). This
avoids the problem where NTFS on the P-VOL will be split in an
inconsistent state because Windows Server delays the I/O for
dismounting.
The following examples show the sync subcommand used as an option of
the pairsplit command.
In the example in
D: is written to disk; all pairs in the specified group are split (status =
PSUS); and read/write access is enabled for all S-VOLs in the specified
group.
•
pairsplit –x sync
In the example in
harddisk2 and harddisk3 is written to disk, all pairs in the specified group
are deleted (status = SMPL), which enables read/write access for all
secondary volumes.
•
pairsplit –x sync
