DescriptionScreen element
Fence level of target device (Pair volume). Displays one of
the following:
Fence Level
• ASYNC for asynchronous communications
• DATA, STATE, or NEVER for synchronous
communications
• JNL for continuous access journal based transactions
Journal ID of the journal group associated with the P-VOL
or S-VOL.
JNL-ID
CTG ID, which guarantees consistency in the sequence of
asynchronous data transfers for a remote copy volume
group.
CTG-ID
Host port assigned for the P-VOL.P-VOL Host Port
Host port assigned for the S-VOL.S-VOL Host Port
CLPR based on the associated volume type (P-VOL or
S-VOL) manages cache for the continuous access
transactions.
CLPR
MP blade based on the associated volume type (P-VOL or
S-VOL) processes requests for the continuous access
transactions.
MP Blade
RAID group to which volume type (P-VOL or S-VOL) the
LDEV belongs.
RG
RAID classification for the RAID group is determined based
on the associated volume type (P-VOL or S-VOL).
RAID Level
NOTE: In HP XP P9000 Performance Advisor v6.0 and earlier versions, the CA table displays
only those pairs that have the mirror IDs configured as 0.
CA link status metrics
Select the row to see the performance metrics of PVOL or SVOL (based on the volume type). If
journals are displayed in the selected row, the journal group and volume details are also displayed.
If a CTG-ID is displayed in the selected row, the CTG performance data is displayed in “CA volume
performance data and journal information” (page 202). To view continuous access journals and
volumes data, see “CA journal” (page 204) and “CA journal volumes” (page 205). You can also
click a particular record to highlight the record and then click Plot Chart to choose the metrics and
view the respective performance graphs.
“CA volume performance data and journal information” (page 202) describes the data displayed:
