Figure 1-34: Pairdisplay Command -v pid Option
The output of the pairdisplay command with –v pid includes:
• PID: Shows the pool ID.
• POLS: The status of the pool is shown as below.
POLN: Shows that the status of the pool is normal.
POLF: Shows that the usage rate of the pool exceeds the set threshold
value.
• U(%): The whole capacity of the pool is made into 100% and the
usage rate is shown.
• SSCNT: Shows the number of SnapShot Volume (V-VOL) in the pool.
• Available(MB): Shows the available capacity for the volume data on
the pool (in MB).
• Capacity(MB): Shows the total capacity in the pool (in MB).
• Seq#: Shows the serial number of the array.
• Num: Shows the number of LU configured the pool.
• LDEV: Shows the first number of LU configured the pool.
• H(%): Shows the threshold rate being set to the pool as High water
mark. ‘Unknown’ will be shown as ‘-’.
Checking pair currency (paircurchk)
The TrueCopy or TCE paircurchk command checks the currency of the
TrueCopy or TCE secondary volumes by evaluating the data consistency
based on pair status and fence level.
specifies the data
consistency for each possible state of a TrueCopy or TCE volume. A paired
volume or group can be specified as the target of the paircurchk command.
The paircurchk command assumes that the target is an S-VOL. If the
paircurchk command is specified for a group, the data consistency of each
volume in the group is checked, and all inconsistent volumes are found in
the execution log file and displayed. Paircurchk is also executed as part of
the TrueCopy or TCE horctakeover command (see next section).
TrueCopy and TCE support the paircurchk command. The paircurchk
command may be executed in the cases where it is performed by you
specification and the SVOL_Takeover processing by the horctakeover
command.
