212 Chapter 4 Performing CCI Operations
Parameter Value
Options -h: Displays Help/Usage and version information.
-q: Terminates the interactive mode and exits the pair volume check command.
-z or -zx (OpenVMS cannot use the -zx option): Makes the pairdisplay command enter the interactive mode.
The -zx option guards performing of the HORCM in the interactive mode. When this option detects a HORCM
shut down, interactive mode terminates.
-I[H][M][instance#] or -I[TC][SI][instance#] Specifies the command as [HORC]/[HOMRCF], and used for
specifying instance# of HORCM.
-g : Specifies the 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 : This option is used to specify 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] [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.
- FHORC [MU#] or -FCA [MU#]: Forcibly specifies a cascading TrueCopy volume for specified pair logical
volumes on ShadowImage environment. If the -l option is specified, this option displays status of a cascading
TrueCopy volume on a local host (near site). If no -l option is specified, this option displays status of a
cascading TrueCopy volume on a remote host (far site). This option cannot be specified with -m
option on the same command line.
-FMRCF [MU#] or -FBC [MU#]: Forcibly specifies a cascading ShadowImage volume for specified pair logical
volumes on TrueCopy environment. If the -l option is specified, this option displays status of a cascading
ShadowImage volume on a local host (near site). If no -l option is specified, this option displays status of a
cascading ShadowImage volume on a remote host (far site). This option cannot be specified with -m
option on the same command line.
-d[g] [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 “ 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.
-c: Checks the configuration of the paired volume connection path (physical link of paired volume among the
servers) and displays illegal pair configurations. If this option is not specified, the status of the specified paired
volume is displayed without checking the path configuration.
-l: Displays the paired volume status of the local host (which issues this command).
-fx: Displays the LDEV ID as a hexadecimal number.
-fc: Displays copy operation progress, sidefile percentage, bitmap percentage, or UR journal percentage.
Displays PFUL/PFUS forTrueCopy Async/UR. Used to confirm SSWS state as indication of SVOL_SSUS-
takeover after.
-fd: Displays the relation between the Device_File and the paired volumes, based on the group (as defined in
the local instance configuration definition file). If Device_File column shows “Unknown” to either the local or
the remote HOST (instance) then it shows a volume which is not recognized on own HOST, and pair operation
are rejected (except the local option such as “-l”) in protection mode. Display example:
# pairdisplay -g oradb -fd
Group PairVol(L/R) Device_File M ,Seq#,LDEV#.P/S,Status, Seq#,P-LDEV# M
oradb oradev1(L) c0t3d0 0 35013 17..P-VOL COPY, 35013 18 -
oradb oradev1(R) c0t3d1 0 35013 18..S-VOL COPY, 35013 17 -
-fm: Displays the Bitmap mode to output of M column.
-fe: Displays the serial# and LDEV# of the external LUNs mapped to the LDEV and additional information for
the pair volume. This option displays the information above by adding to last column, and then ignores the
format of 80 column. This option will be invalid if the cascade options (-m all,-m cas) are specified.
Display example for TrueCopy:
# pairdisplay -g horc0 -fdxe
Group ... LDEV#.P/S,Status,Fence,Seq#,P-LDEV# M CTG JID AP EM E-Seq# E-LDEV#
horc0 ... 41.P-VOL PAIR ASYNC ,63528 40 - 0 - 2 - - -
horc0 ... 40.S-VOL PAIR ASYNC ,----- 41 - 0 - - - - -
Display example for ShadowImage/Snapshot:
# pairdisplay -g horc0 -fe
Group ... Seq#,LDEV#.P/S,Status, Seq#,P-LDEV# M CTG CM EM E-Seq# E-LDEV#
