Primary Volume
|
The P-VOL information.
Values:
- LDEV
ID The P-VOL's LDEV
identification number. Click to open the LDEV Properties window. Use this
window to search for P-VOL information.
- LDEV
Name The P-VOL's LDEV
name.
- CLPR The P-VOL's CLPR
ID.
- Virtual Storage Machine
The model type and serial number of the virtual storage
machine to which the P-VOL belongs.
- Virtual LDEV ID The
identification number of the P-VOL’s virtual LDEV. If no
virtual LDEV ID is assigned, a blank is displayed.
- Virtual Device Name The
name of the P-VOL’s virtual device, in a combined format of
"virtual emulation type", "number of virtual LUSE volumes",
and "virtual CVS attribute". Each of these three items is
displayed only if it is specified. If none of them are
specified, a blank is displayed.
- Virtual SSID The
virtual SSID of the P-VOL. If no virtual SSID is specified,
a blank is displayed.

Copy Type
|
The SI volume’s copy type.
Values:
- SI-L1
SI L1 pair
- SI-L2
SI L2 pair
- SIMF
SIz pair
|
|
Snapshot Group
|
The HTI snapshot group name.
If you have not configured a snapshot group for the HTI pair, this item is blank.
|
|
Status
|
The pair status.
For more
information about HTI pair status, see Thin Image Advanced pair status definitions.
|
|
Synchronization Rate (%)
|
For SI
-
If the pair status is COPY(PD)/COPY, COPY(SP)/COPY, or PSUS (SP)/PSUS, the copy progress rate is displayed.
-
If the pair status is PAIR, PSUS, COPY(RS-R)/RCPY, or PSUE, the synchronization rate between P-VOL and S-VOL is displayed.
- If the pair status is COPY(RS)/COPY changed from PSUE, the copy progress rate is displayed.
-
If the pair status is COPY(RS)/COPY changed from other than PSUE, the synchronization rate between P-VOL and S-VOL is displayed.
-
If the pair status is SMPL(PD), a hyphen is displayed.
SIz:
-
If the pair status is PENDING, SP-Pend/TRANS, or V-Split/SUSPVS, the copy progress rate is displayed.
-
If the pair status is DUPLEX, Split/SUSPOP, Resync-R/REVRSY, or Suspend/SUSPER, the synchronization rate between P-VOL and S-VOL is displayed.
-
If the pair status is Resync/PENDING, changed from Suspend/SUSPER, the copy progress rate is displayed.
-
If the pair status is Resync/PENDING, changed from other than Suspend/SUSPER, the synchronization rate between P-VOL and S-VOL is displayed.
-
If the pair status is Deleting/TRANS, a hyphen is displayed.
For Thin Image Advanced pairs, a hyphen is displayed.
For Thin Image pairs, the displayed
information depends on whether the cascade attribute is enabled
or disabled.
- For Thin Image pairs where the cascade attribute is
enabled, the following information is displayed depending on
the pair status:
- If the pair
status is PAIR, PSUS, or PSUE, the pair
synchronization rate shows the rate that current
S-VOL data matches that of the next generation of
the S-VOL. If the S-VOL is the latest one, the
synchronization rate is computed by comparing the
S-VOL with the P-VOL.
- If the pair
status is COPY, PSUS(SP), RCPY, or SMPL(PD), the
progress rate of each process is displayed.
- For Thin Image
pairs with the cascade attribute disabled, the pair
synchronization rate that the current S-VOL data
matches that of the next generation of the S-VOL is
displayed. If the S-VOL is the latest one, the
synchronization rate is computed by comparing the
S-VOL with the P-VOL.
To display the
progress rate, enable Display Progress
Rate of the system option #17 in the
Edit Local Replica
Options window.
- If the pair status is COPY, RCPY,
or SMPL(PD), the progress rate for each process is
displayed.
- If the pair status is PAIR, PSUS,
or PSUE, the synchronization rate is displayed in
the same way as when the system option #17 is not
set.
For information about how to
enable the local replica options, see Changing local replica
options that affect Thin Image Advanced
performance.

Secondary Volume
|
The S-VOL information.
Values:
- LDEV
ID The S-VOL's LDEV
identification number. Click to open the LDEV Properties
window.
- LDEV
Name The S-VOL's LDEV
name.
- CLPR
The S-VOL's CLPR ID.
- Virtual Storage Machine
The model type and serial number of the virtual storage
machine to which the S-VOL belongs.
- Virtual LDEV ID The
identification number of the S-VOL’s virtual LDEV. If no
virtual LDEV ID is assigned, a blank is displayed.
- Virtual Device Name The
name of the S-VOL’s virtual device, in a combined format of
"virtual emulation type", "number of virtual LUSE volumes",
and "virtual CVS attribute". Each of these three items is
displayed only if it is specified. If none of them are
specified, a blank is displayed.
- Virtual SSID The
virtual SSID of the S-VOL. If no virtual SSID is specified,
a blank is displayed.
|
|
Mirror Unit
|
The mirror unit number.
|
|
Cascade
|
Indicates whether a cascaded pair can be created
- Enabled Cascaded pairs can be created.
- Disabled Cascaded pairs cannot be created.
A hyphen (-) is displayed for non-HTI pairs.
|
|
Type
|
The pair type.
- Snapshot A pair with the snapshot attribute.
- Clone
A pair with the clone attribute or diff clone attribute.
Thin Image Advanced does not support cloning.
In the TI Pairs window, if Diff Compare
Volume displays the LDEV ID, the diff clone
attribute is set for the pair. If Diff Compare
Volume displays a hyphen (-), the clone
attribute is set for the pair.
A hyphen (-) is displayed for non-HTI pairs.
|
|
Topology ID
|
The topology ID, which indicates the layer of the pair based on the mirror unit. The topology ID consists of the LDEV ID of the volume (root volume for Thin Image pairs) and the mirror unit number.
