Commands Reference, Volume 5, s - u
syncvg_Command
Purpose
Synchronizes logical volume copies that are not current.
Syntax
syncvg [ -f ] [ -i ] [ -H ] [ -P NumParallelLps ] { -l |
-p | -v } Name ...
Description
The syncvg command synchronizes the physical partitions, which
are copies
of the original physical partition, that are not current. The
syncvg
command can be used with logical volumes, physical volumes, or
volume
groups, with the Name parameter representing the logical vol-
ume name,
physical volume name, or volume group name. The synchroniza-
tion process
can be time consuming, depending on the hardware characteris-
tics and the
amount of data.
When the -f flag is used, a good physical copy is chosen and
propagated to
all other copies of the logical partition, whether or not they
are stale.
Using this flag is necessary in cases where the logical volume
does not
have the mirror write consistency recovery.
Unless disabled, the copies within a volume group are synchro-
nized
automatically when the volume group is activated by the vary-
onvg
command.
Note:
For the sycnvg command to be successful, at least one good
copy of the
logical volume should be accessible, and the physical volumes
that
contains this copy should be in ACTIVE state. If the -f option
is used,
the above condition applies to all mirror copies.
If the -P option is not specified, syncvg will check for the
NUM_PARALLEL_LPS environment variable. The value of NUM_PARAL-
LEL_LPS will
be used to set the number of logical partitions to be synchro-
nized in
parallel.
Flags
Specifies a good physical copy is chosen and
propagated
-f to all other copies of the logical parti-
tion, whether or
not they are stale.
Postpones writes for this volume group on
other active
concurrent cluster nodes until this sync op-
eration is
-H complete. When using the -H flag, the -P
flag does not
require that all the nodes on the cluster
support the -P
flag. This flag is ignored if the volume
group is not
varied on in concurrent mode.
-i Reads the names from standard input.
-l Specifies that the Name parameter represents
a logical
volume device name.
-p Specifies that the Name parameter represents
a physical
volume device name.
Numbers of logical partitions to be synchro-
nized in
parallel. The valid range for NumParallelLps
is 1 to 32.
NumParallelLps must be tailored to the ma-
chine, disks in
the volume group, system resources, and vol-
ume group
mode.
-P NumParallelLps When a volume group is varied on in concur-
rent mode, all
other cluster nodes that have this volume
group varied
must be at least AIX 4.3.0, otherwise syncvg
will ignore
this option and continue.
Note:
See Description above for more information.
-v Specifies that the Name parameter represents
a volume
group device name.
Examples
1. To synchronize the copies on physical volumes hdisk04 and
hdisk05,
enter:
syncvg
-p hdisk04 hdisk05
2. To synchronize the copies on volume groups vg04 and vg05,
enter:
syncvg
-v vg04 vg05
