showdatasync(1M)

NAME

showdatasync- display the status of SSP data synchronization for failover

SYNOPSIS

showdatasync

-l|

-Q

DESCRIPTION

showdatasync provides the current status of files propagated (copied) from the main SSP to its spare. Data propagation synchronizes data on the spare SSP with data on the main SSP, so that the spare SSP is current with the main SSP if an automatic failover occurs.

OPTIONS

The following options are supported:

-l: Lists the files in the current data propagation list. See the EXTENDED DESCRIPTION section for details on the information displayed.
-Q: Lists the files queued for propagation. Each file name includes the absolute path to the file.

EXTENDED DESCRIPTION

This section describes the information displayed by the showdatasync command.

If you do not specify an option with the showdatasync command, the following information is displayed:

File Propagation Status:
Active File:
Queued files:

where

File Propagation Status

Displays the current status of data synchronization:

Active indicates the data synchronization process is enabled and functioning normally.
Disabled indicates the data synchronization process has been disabled because automatic SSP failover was disabled.
Failed indicates the data synchronization process cannot currently propagate files to the spare SSP even though an SSP failure was detected.

Active File

Displays either the absolute path of the file currently being propagated or a - (dash) indicating that the link is idle.

Queued files

Specifies the number of files to be propagated but not yet processed.

If you specify the -l option with the showdatasync command, each entry in the data propagation list is displayed in the format Time Propagated, Interval, File where

Time Propagated: Indicates the last time that the file was propagated from the main SSP to the spare.
Interval: Specifies the interval, in minutes, between checks for file modification. The default interval is 60 minutes.
File: Provides the absolute path and name of the propagated file.

EXIT STATUS

The following exit values are returned:

0: Successful completion.
>0: An error occurred.
