30 Replication commands
Description
Specifies the paired logical volume name defined in the configuration definition file. When this option
is specified, the command is executed for the specified paired logical volumes.
-d[g] <raw_device> [MU#]: Searches a group on the configuration definition file (local instance) for
the specified raw_device, and if the specified raw_device is contained in the group, the target volume
is executed as the paired logical volume (-d) or group (-dg). This option is effective without specification
of "-g <group>" option. If the specified the raw_device is contained in two or more groups, the
command is executed on the first group.
-d[g] <seq#> <LDEV#> [MU#]: Searches a group on the configuration definition file (local instance)
for the specified LDEV, and if the specified LDEV is in the group, the target volume is executed as
the paired logical volume (-d) or group (-dg). This option is effective without specification of "-g
<group>" option. If the specified LDEV is contained in two or more groups, the command is executed
on the first group. The <seq #> <LDEV #> values can be specified in hexadecimal (by addition of
"0x ") or decimal notation.
Continuous Access Synchronous only.
Specifies a mode of access to the S-VOL after paired volumes are split. The -r option (default) allows
read-only to the S-VOL. The -rw option enables read and write access to the S-VOL.
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
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.
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.
-R[S][B] (Specifiable for HORC only): This option is used to bring the secondary volume forcibly into
simplex mode. It is issued by the secondary host if the host possessing the primary volume goes down
due to a failure.
-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 and Continuous Access Journal only.
For Continuous Access Synchronous Synchronous, 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 P-VOL data changes by the host possessing the primary volume.
For Continuous Access Asynchronous/JNL, this option is used to suspend and purge the remaining
data into SideFile/Journal like link failure (PSUE) without updating S-VOL. 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 S-VOL as file system (For example, UFS, NTFS, HANFS), then an
FSCK(CHKDSK) is necessary before mounting the volume even after the P-VOL is unmounted.
When this command cannot utilize the remote host for 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 volumes are able to split only S-VOL.)
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.
Business Copy and Snapshot only.
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.) For <size>, specify the copy pace for the pairsplit (range = 1 to 15 track extents). If not
specified, the value used for paircreate is used.
