Data recovery for PSUE using TrueCopy and TCE
When a pair was suspended (PSUE) due to a failure in the array, collect the
CCI system log files and then call the Hitachi maintenance personnel The
maintenance personnel will remove the error cause of the array. After the
error cause has been removed, the system administrator must recover the
pair using the CCI commands.
Recovering the pair
Resynchronization in the direction of P-VOL to S-VOL enables to recover a
TrueCopy or TCE pair. (The resynchronization cannot be performed in the
direction of S-VOL to P-VOL.) However, when a pair was suspended (status
= PSUE) without a failure in the system, once release the pair and create
the pair again. Please recover the pair following the procedure in Figure 2-
3 on page 2-7 for TrueCopy or Figure 2-5 on page 2-12 for TCE.
•
NOTE: In the case of TCE, the resynchronization of the S-VOL with the P-
VOL is required when the P-VOL status is changed to PFUS because the
amount of the data in the primary data pool exceeds the capacity allowed
to be used or the S-VOL status is changed to PSUS(N) as well as the P-VOL
status is changed to PSUE. The PSUS(N) means the Read/Write operation
cannot be performed; and it is a status in which the S-VOL data is not
restored even when the SVOL-Takeover operation is performed.
