Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access XP P9000 for Linux B.12.00.00

The pairdisplay -fe is 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
Group Seq#, LDEV# P/S,Status, Fence, %, P-LDEV# M CTG JID AP EM E-Seq# E-LDEV#
oradb 30053 64 PVOL PAIR Never, 75 C8 - 1 0 2
oradb 30054 C8 SVOL PAIR Never, 64 - - 1 0
Viewing the journal volumes information using the “raidvchkscan” command
The raidvchkscan command 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 12 shows the illustration for Q-Marker and Q-CNT. The following terms define the meaning
of the 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.
• In case of the S-JNL, Q-Marker shows the latest sequence number putting on the cache.
• Q-CNT: Displays the number of remaining Q-Marker of a journal group.
