Determining the State of an Individual Hitachi TrueCopy or Universal Replicator Device Group

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.

Table 2–1 Individual Hitachi TrueCopy and Universal Replicator Device Group States


Output of `pairvolchk`	Individual Device Group State
`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.
