DescriptionOption
#> values can be specified in hexadecimal (add the '0x' prefix) or decimal notation. For XP7, specify
the number of which 300,000 is added to the serial number for <seq#>.
Continuous Access Synchronous/Continuous Access Synchronous Async/Continuous Access Journal
only.
-r or -rw
Specifies a mode of access to the SVOL after paired volumes are split. The -r option (default) allows
read-only to the SVOL.
The -rw option enables read and write access to the SVOL.
Selects simplex mode (deletes the pair). When the pairing direction is reversed among the hosts (for
example, disaster recovery), this mode is established once, and then the paircreate command is
-S
issued. When splitting a pair, whether or not you can change the pair status of S-VOL, changing the
pair status of P-VOL to SMPL takes priority. Therefore, if the pair status of S-VOL cannot be changed
to SMPL, the pair status of P-VOL might not correspond with that of S-VOL. When a path failure has
occurred, the pair status of S-VOL cannot be changed to SMPL.
Continuous Access Synchronous/Continuous Access Synchronous Async/Continuous Access Journal
only.
-R [S] [B]
Brings the secondary volume into the simplex mode forcibly. It is issued by the secondary host, if the
host possessing the primary volume is down or has failed.
-RS option is used to bring the secondary volume forcibly into SSWS mode.
-RB option is used to back the secondary volume forcibly from SSWS into PSUS(PSUE)(SSUS) mode.
This allows backing up to the primary volume if you want to back from the secondary host in the
SSWS state on Link failure to the primary host.
Continuous Access Synchronous/Continuous Access SynchronousAsync/Continuous Access Journal
only.
-P
For Continuous Access Synchronous Sync, this option is used to bring the primary volume forcibly
into write disabled mode like PSUE with 'fence=data'. It is issued by the secondary host to disable
PVOL data changes by the host possessing the primary volume.
For Continuous Access Synchronous Async/Continuous Access Journal, this option is used to suspend
and purge the remaining data into SideFile/Journal like link failure (PSUE) without updating SVOL.
This lets you stop journal operations forcibly when the journal utilization traffic becomes high. This
is the same for the case of disaster that S-VOL data is not up to date, but it allows to specify '-rw -P'
for writing enable. In that situation, if you are using the SVOL as file system (that is, UFS, NTFS,
HANFS), then an FSCK(CHKDSK) is necessary before mounting the volume even after the PVOL is
unmounted.
When the remote host cannot be used due to host down, this option enables a pairsplit operation
by a local host only. Except the -R option, the target volume of a local host must be P-VOL. (Business
Copy or Snapshot volumes are able to split only SVOL.)
-l
Suppresses messages to be displayed when this command is executed. It is used to execute a
command from a user program. This option must be specified at the beginning of a command
argument. The command execution log is not affected by this option.
-nomsg
Business Copy only.-C <size>
Copies difference data retained in the primary volume into the secondary volume, then enables
reading and writing from/to the secondary volume after completion of the copying. (This is the default
option.) If not specified, the value used for paircreate or pairresync command is used. In Business
Copy, when you specify 1 or 2, the copy pace is slow, when you specify 3, the copy pace is medium.
And when you specify 4, the copy pace is fast.
Business Copy only.-E
Suspends a paired volume forcibly when a failure occurs. Not normally used.
When this option is specified, the copy pace is set to the default value (3: medium).
Forcibly specifies a cascading remote copy volume for specified volume pair on local copy
environment. If the -l option is specified, a cascading remote copy volume is split on a local host
-FHORC [MU#]
or -FCA [MU#]
(near site). If the -l option is not specified, a cascading remote copy volume is split on a remote host
