An individual Hitachi TrueCopy or Universal Replicator device group can be in one of the following states:
SMPL
Regular Primary
Regular Secondary
Takeover Primary
Takeover Secondary
The state of a particular device group is determined by using the value that is returned by the pairvolchk -g devicegroup -ss command. The following table describes the device group state associated with the values returned by the pairvolchk command.

11 = SMPL |
SMPL |
22 / 42 = PVOL_COPY 23 / 42 = PVOL_PAIR 26 / 46 = PVOL_PDUB 47 = PVOL_PFUL 48 = PVOL_PFUS |
Regular Primary |
24 / 44 = PVOL_PSUS 25 / 45 = PVOL_PSUE For these return codes, determining the individual device group category requires that the horcmd process be active on the remote cluster so that the remote-pair-state for this device group can be obtained. |
Regular Primary, if remote-cluster-state !=SSWS or Takeover Secondary, if remote-cluster-state == SSWS SSWS, when you use the pairdisplay -g devicegroup -fc command. |
32 / 52 = SVOL_COPY 33 / 53 = SVOL_PAIR 35 / 55 = SVOL_PSUE 36 / 56 = SVOL_PDUB 57 = SVOL_PFUL 58 = SVOL_PFUS |
Regular Secondary |
34 / 54 = SVOL_PSUS |
Regular Secondary, if local-cluster-state !=SSWS or Takeover Primary, if local-cluster-state == SSWS SSWS, when you use the pairdisplay -g devicegroup -fc command. |
