DescriptionField
The MU number of the BC pair formed with the P-VOL. MU#s are mirror unit numbers. The
storage system assumes the same numbers of P-VOLs as S-VOLs. For example, when a
MU
P-VOL is paired with three S-VOLs, though just one P-VOL exists, the storage system assumes
that there are three P-VOLs. These virtual P-VOLs are mirror units, MUs.
The pair status. For more information, see “Pair status definitions” (page 53).Status
The S-VOL information in AAA-BB-CCC(XX:YY:ZZ) format.S-VOL
• AAA is the port ID (cluster and channel number)
• BB is the group number of host group
• CCC is the LU number
• XX:YY:ZZ is the LDKC number:CU number:LDEV number
Only one path is listed, even for LUs with more than one. The path is connected to the first
port configured for the path.
The S-VOL’s consistency group number. If you have not set a consistency group for the
S-VOL, dashes (---) are shown.
CTG
Indicates whether the S-VOL has been written to and whether it can be read.SvolMode
• Dashes (---) indicate that it has not been written to and can be read.
• W indicates that it has been written to. The S-VOL pair status is PSUS(SP)/PSUS or PSUS,
and the host writes to it.
• N indicates that it cannot be read because of the RAID Manager -m noread specification.
Indicates the speed that data is copied according to pair status.Copy Pace
• Slower, Medium, or Faster is shown if the pair status is COPY(PD)/COPY,
COPY(SP)/COPY, PSUS(SP)/PSUS, COPY(RS)/COPY, or COPY(RS-R)/RCPY.
• Dashes (----) display if the pair status is none of the above.
Note: When you create BC pairs by using RAID Manager, the copy pace is set as follows:
• When the track size is 1 or 2, Slower is set.
• When the track size is 3, Medium is set.
• When the track size is 4 to 15, Faster is set.
Indicates the percentage of pair synchronization:Sync
• Dashes (----) display for volumes or pairs in SMPL and SMPL(PD) status.
• The percentage of copied data is shown for pairs in COPY(PD)/COPY, COPY(SP)/COPY,
PSUS(SP)/PSUS, and PSUE status.
• The percentage of identical data in the P-VOL and S-VOL for volumes in PAIR, PSUS,
COPY(RS)/COPY, or COPY(RS-R)/RCPY status.
