Viewing the Continuous Access Journal Status

The following two sections describe using the pairdisplay and raidvchkscan commands for viewing the Continuous Access Journal Status.

Viewing the Pair and Journal Group Information - Raid Manager using the “pairdisplay” Command

The command option “-fe” is added to the Raid Manager pairdisplay command. This option is used to display the Journal Group ID (and other data) of a device group pair. The Journal Group ID shows ‘-’ if the device pair is not in Continuous Access Journal mode. Otherwise, it shows a number.

An example of the pairdisplay command with the “-fe” is as below:

The pairdisplay -feis primarily used for the following: Continuous Access Journal device group consistency set, Journal group ID (JID), and Continuous Access link status (AP).

# pairdisplay -g oradb -fe

Viewing the Journal Volumes Information - Raid Manager using the “raidvchkscan” Command

The raidvchkscancommand supports the option (-v jnl [unit#]) in order to find the journal volume lists, and displays information for the journal volumes.

raidvchkscan { -h -q -z -v jnl [unit#] [ -s Seq# ] [ -f[x ] }

An example of the raidvchkscan command is as follows:

# raidvchkscan –v jnl 0

Figure 34 shows the illustration for Q-Marker and Q-CNT. The following terms define the meaning for contents in the figure.

•JID: Displays the journal group ID.

•MU: Displays the mirror descriptions on the journal group.

•CTG: Displays the consistency group ID.

•JNLS: Displays the following status in the journal group.

◦SMPL: this means the journal volume is no in pair mode or is in deleting state.

◦P(S)JNN: this means “P(S)vol Journal Normal”

◦P(S)JSN: this means “P(S)vol Journal Suspend Normal”

◦PJNF: this means “P(S)vol Journal Normal Full”

◦P(S)JSF: this means “P(S)vol Journal Suspend Full”

◦P(S)JSE: this means “P(S)vol Journal Suspend Error” including Link failure

•AP: shows the number of active path on the initiator port in Continuous Access links.

•Q-Marker: Displays the sequence number in the journal group.

•In case of the P-JNL, Q-Marker shows the latest sequence number on P-JNL volume.
