1—Startup the package after resynchronize the data from

 

the SVOL side to the PVOL side. The risk of using this option

 

is that the SVOL data might not be a preferable one.

 

If the package has been configured for a three data center

 

(3DC) environment, this parameter is applicable only when

 

the package is attempting to start up in either the primary

 

(DC1) or secondary (DC2) data center. This parameter is

 

not relevant in (the third data center) in the recovery cluster.

 

Use this parameter’s default value in the third data center.

AUTO_SVOLPFUS

(Default = 0)

 

This parameter applies when the PVOL and SVOL both have

 

the state of suspended (PFUS) due to the side file reaching

 

threshold while in Asynchronous mode only. When the PVOL

 

and SVOL are in this state, the Continuous Access link is

 

suspended, the data on the PVOL is not remotely protected,

 

and the data on the SVOL will not be current. When starting

 

the package in this state, you run the risk of losing any data

 

that has been written to the PVOL side.

 

Values:

 

0 – (Default) Do NOT startup the package at the secondary

 

site and allowing restart on another node. Require user

 

intervention to either fix the problem by resynchronizing the

 

PVOL and SVOL or force the package to start on this node

 

by creating the FORCEFLAG.

 

1 – Startup the package after making the SVOL writable.

 

The risk of using this option is that the SVOL data might

 

actually be non-current and the data written to the PVOL

 

side after the hardware failure might be loss.

 

This parameter is not required to be set if a package is

 

configured for three data centers environment because three

 

data center does not support Asynchronous mode of data

 

replication. Leave this parameter with its default value in all

 

data centers.

AUTO_SVOLPSUE

(Default = 0)

 

This parameter applies when the PVOL and SVOL both have

 

the state of PSUE. This state combination will occur when

 

there is an Continuous Access link, or other hardware failure,

 

or when the SVOL side is in a PSUE state while we can not

 

communicate with the PVOL side. This will only apply while

 

in the Asynchronous mode.

 

The SVOL side will become PSUE after the Continuous

 

Access link timeout value has been exceeded at which time

 

the PVOL side will try and flush any outstanding data to the

 

SVOL side. If this flush is unsuccessful, then the data on the

 

SVOL side will not be current.

 

Values:

 

0 – (Default) Do NOT startup the package at the secondary

 

site and allow package to try another node. Require user

 

intervention to either fix the problem by resynchronizing the

 

PVOL and SVOL or force the package to start on this node

 

by creating the FORCEFLAG file.

 

1 – Startup the package on the SVOL side. The risk of using

 

this option is that the SVOL data might actually be
