HP XP P9000 RAID Manager Reference Guide (T1610-96061, January 2014)

DescriptionOption
In Continuous Access Synchronous Z, when you specify the number less than or equal to 3, the
copy speed is 3 tracks. When you specify the number more than or equal to 4, the copy speed is
15 tracks. In Business Copy, when you specify 1 or 2, the copy speed is slow, when you specify
3, the copy speed is medium, and when you specify 4, the copy speed is fast.
Creates paired volumes without copying data when the data consistency of simplex volumes is
assured by the user.
-nocopy
Note: This option cannot be specified for Business Copy or Business Copy Z.
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
Business Copy/Business Copy/Snapshot only.-split
Splits the paired volume after the initial copy operation is complete. This option will return after
changed the state in PVOL_PSUS & SVOL_COPY immediately, and SVOL state is changed to
'SVOL_SSUS' after all data is copied.
Specifies the mode.-m <mode>
mode = noread (Business Copy only): Specifies the noread mode for hiding the secondary volume.
The secondary volume becomes read-disabled when this mode option is specified. The secondary
volume is read-enabled when this mode option is omitted. Note: The primary volume becomes
read-disabled during a reverse resync operation (restore option of pairresync command).
mode = cyl (XP1024/XP128 Disk Array Continuous Access Synchronous/Continuous Access
Synchronous Async/Continuous Access Journal only): sets bitmap difference management to cylinder.
mode = trk (XP1024/XP128 Disk Array Continuous Access Synchronous/Continuous Access
Synchronous Async/Continuous Access Journal only): sets bitmap difference management to track.
Note: If the mode (cyl or track) is not specified, the default values are used: default is track for
OPEN-3 and OPEN-9; default is cylinder for OPEN-E and OPEN-L.
Note: For Continuous Access Synchronous/Continuous Access Synchronous Async/Continuous
Access Journal volumes paired between XP1024/XP128 Disk Array storage systems, the bitmap
tables are managed at the Cylinder level, even if Track is specified.
mode=grp [CTGID] (XP1024/XP128 Disk Array Business Copy/Business Copy/Snapshot/Auto
LUN only). Makes a group for splitting all Business Copy pairs specified in a group. Like a Continuous
Access Synchronous Async/Continuous Access Journal consistency group, Business Copy guarantees
data consistency among multiple LUNs in a group at a single point in time when doing a split using
the 'pairsplit -g <group>' command (except '-S' or '-E' option).
A CTGID (CT Group ID) is assigned automatically if you do not specify the 'CTGID' option in this
command. If 'CTGID' is not specified and the maximum number of CT groups already exists, an
EX_ENOCTG error is returned. Therefore, the 'CTGID' option can forcibly assign a volume group
to an existing CTGID (for example, 0-127 on XP24000/XP20000 Disk Array).
For the detail, please refer to “Restrictions on specified volumes with '–m grp' option.”.
Note: This option cannot be specified with '-split' option in the same command.
mode = cc (Auto LUN only): Specifies the Cruising Copy mode for volume migration.
The -vl option specifies 'local', and copies from the local instance LU(PVOL) to the remote instance
LU(SVOL). An original volume as the local instance LU is migrated from PVOL to SVOL, and the
physical volume mapping between PVOL and SVOL is swapped after copied.
The -vr option specifies 'remote', and copies from the remote instance LU(PVOL) to the local instance
LU(SVOL). An original volume as the remote instance LU is migrated from PVOL to SVOL, and the
physical volume mapping between PVOL and SVOL is swapped after copied. During maintenance
work on the storage system (SVP is in modify mode), this operation cannot be completed.
Notes:
This option cannot be specified with the '-split' option in the same command.
This option ignores the '-c <size>' option.
Continuous Access Journal only. You can use this option when specifying a journal ID for PVOL.-jp <id>
Both the -jp <id> and -js <id> options are valid when the fence level is set to 'ASYNC', and each
journal ID is automatically bound to the CTGID.
