Syntax; Options And Parameters - HP StorageWorks P9000 Reference Manual

When a client issues the pairsyncwait command, this command is placed on the queue buffer for
waiting in the HORCM daemon as a command request. HORCM gets the latest sequence # from
the MCU sidefile and the sequence # whose block was transferred and stored in the DFW area
of RCU with data consistency, and compares the latest sequence # of MCU sidefile with the
sequence # of the RCU DFW area within the term. HORCM replies return codes to this command,
when the write of MCU sidefile was stored in RCU DFW area.
Using this function, a client can confirm that a commit() has reached the remote site, and also the
backup utility on a remote site can split the cascading Business Copy volumes (Continuous Access
Asynchronous/Cnt Ac-J to Continuous Access Asynchronous/Business Copy/Cnt Ac-J) without
splitting Continuous Access Asynchronous/Cnt Ac-J.
More robust systems need to confirm the data consistency between the Continuous Access
Asynchronous/Cnt Ac-J PVol and S-VOL. In DB operations (e.g., Oracle), the commit() of DB
transaction (see the following figure) is needed to confirm that a last writing for the commit() on a
local site reached the remote site by using RAID Manager-unique API command.

Options and parameters

Option
-h
-q
-z or -zx
102 Replication commands
Description
Displays Help/Usage and version information.
Terminates the interactive mode and exits the command.
Makes the raidar command enter the interactive mode. The -zx option guards performing of the
HORCM in the interactive mode. When this option detects a HORCM shutdown, interactive mode
terminates.
OpenVMS cannot use the -zx option.
