Option -I [H] [M] [instance#] or -I [TC] [SI] [instance#] Description Specifies the command as [HORC]/[HOMRCF] or [Continuous Access Synchronous]/[Business Copy], and used when specifying the RAID Manager instance number. -g Used to specify a group name defined in the configuration definition file. This option must always be specified. The command is executed for the specified group unless the -d option is specified. -d Specifies a 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] [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 " option. If the specified the raw_device is contained in two or more groups, the command is executed on the first group. -d[g] Searches a group on the configuration definition file (local instance) for the specified LDEV, and if [MU#] the specified LDEV 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 " option. If the specified LDEV is contained in two or more groups, the command is executed on the first group. The values can be specified in hexadecimal (by addition of "0x ") or decimal notation. -FHORC [MU#] or -FCA [MU#] Forcibly specifies a cascading Continuous Access Synchronous volume for specified pair logical volumes on Business Copy environment. If the -l option is specified, this option resyncs a cascading Continuous Access Synchronous volume on a local host (near site). If no -l option is specified, this option resyncs a cascading Continuous Access Synchronous volume on a remote host (far site). The target Continuous Access Synchronous volume must be a P-VOL, the -swapp option cannot be specified. -FMRCF [MU#] or -FBC [MU#] Forcibly specifies a cascading Business Copy volume for specified pair logical volumes on Continuous Access Synchronous environment. If the -l option is specified, this option resyncs a cascading Business Copy volume on a local host (near site). If no -l option is specified, this option resyncs a cascading Business Copy volume on a remote host (far site). The target Business Copy volume must be a P-VOL. -swaps with -FHORC [MU#] Swaps the cascading Cnt Ac-J volume from the primary node for failback. In failback operation from 3DC Cascade Site Failure, if you want to failback to DC1 from DC3 directly, it is necessary to operate all cascading volume from DC1. In order to make this operation possible, RAID Manager supports the "pairresync -swaps -FHORC" option that swaps the Cnt Ac-J volume on the cascading CA-Sync/Cnt Ac-J volume. -c -nomsg -l -restore Specifies the copy pace for the resync operation (range = 1 to 15 track extents, default = 3). If not specified, the value used for paircreate is used. Suppresses messages to be displayed when this command is executed. It is used to execute this 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. When this option cannot utilize the remote host for host down, this option enables a pairresync operation by the local host only. The target volume of the local host must be P-VOL. (Business Copy volumes are able to resync only S-VOL.) Business Copy only. Performs reverse resync (from secondary volume to primary volume). -swaps Continuous Access Synchronous and Journal Software. Executed from the S-VOL side when there is no host on the P-VOL side to help. Typically executed in PSUS state to facilitate "fast failback" without requiring a full copy. For both -swaps and -swapp, the delta data from the original S-VOL becomes dominant and is copied to the original P-VOL, then the S/P-VOL designations are swapped. pairresync 35

Description
Option
Specifies the command as [HORC]/[HOMRCF] or [Continuous Access Synchronous]/[Business Copy],
and used when specifying the RAID Manager instance number.
-I [H] [M]
[instance#]
or
-I [TC] [SI]
[instance#]
Used to specify a group name defined in the configuration definition file. This option must always
be specified. The command is executed for the specified group unless the -d <pair Vol> option is
specified.
-g <group>
Specifies a 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 <pair Vol>
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]
<raw_device>
[MU#]
Searches a group on the configuration definition file (local instance) for the specified LDEV, and if
the specified LDEV 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 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.
-d[g] <seq#>
<LDEV#> [MU#]
Forcibly specifies a cascading Continuous Access Synchronous volume for specified pair logical
volumes on Business Copy environment. If the -l option is specified, this option resyncs a cascading
Continuous Access Synchronous volume on a local host (near site). If no -l option is specified, this
option resyncs a cascading Continuous Access Synchronous volume on a remote host (far site). The
target Continuous Access Synchronous volume must be a P-VOL, the -swapp option cannot be
specified.
-FHORC [MU#]
or -FCA [MU#]
Forcibly specifies a cascading Business Copy volume for specified pair logical volumes on Continuous
Access Synchronous environment. If the -l option is specified, this option resyncs a cascading Business
Copy volume on a local host (near site). If no -l option is specified, this option resyncs a cascading
Business Copy volume on a remote host (far site). The target Business Copy volume must be a P-VOL.
-FMRCF [MU#]
or -FBC [MU#]
Swaps the cascading Cnt Ac-J volume from the primary node for failback.
In failback operation from 3DC Cascade Site Failure, if you want to failback to DC1 from DC3
directly, it is necessary to operate all cascading volume from DC1.
In order to make this operation possible, RAID Manager supports the “pairresync -swaps -FHORC”
option that swaps the Cnt Ac-J volume on the cascading CA-Sync/Cnt Ac-J volume.
-swaps with
-FHORC [MU#]
Specifies the copy pace for the resync operation (range = 1 to 15 track extents, default = 3). If not
specified, the value used for paircreate is used.
-c <size>
Suppresses messages to be displayed when this command is executed. It is used to execute this
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
When this option cannot utilize the remote host for host down, this option enables a pairresync
operation by the local host only. The target volume of the local host must be P-VOL. (Business Copy
volumes are able to resync only S-VOL.)
-l
Business Copy only.
Performs reverse resync (from secondary volume to primary volume).
-restore
Continuous Access Synchronous and Journal Software.
Executed from the S-VOL side when there is no host on the P-VOL side to help. Typically executed in
PSUS state to facilitate “fast failback” without requiring a full copy. For both -swaps and -swapp, the
delta data from the original S-VOL becomes dominant and is copied to the original P-VOL, then the
S/P-VOL designations are swapped.
