Explanation of terms in Table 4.16:
XXX = Pair status of P-VOL returned by "pairvolchk -s" or "pairvolchk -s -c" command
YYY = Pair status of S-VOL returned by "pairvolchk -s" or "pairvolchk -s -c" command
PAIR STATUS = Since the P-VOL controls status, PAIR STATUS is reported as PVOL_XXX
(except when the P-VOL's status is Unknown).
PVOL-PSUE = PVOL-PSUE-takeover
PVOL-SMPL = PVOL-SMPL-takeover
Nop = Nop-takeover
Swap = Swap-takeover. When the horctakeover command execution succeeds, the state
transitions to the indicated ( ) state number.
SVOL SVOL-SSUS takeover or Swap-takeover. In case of a host failure, this function
=
executes Swap-takeover. In case of an ESCON/fibre-channel or P-VOL site failure, this
function executes SVOL-SSUS-takeover.
SVOL_E
=
SVOL_E*
=
When the horctakeover command execution succeeds, the state transitions to the
indicated ( ) state number. For example, if the HA control script sees SVOL_PAIR at the
local (near) volume and PVOL_PAIR at the remote (far) volume (like state 16 above), it
will perform a swap takeover which will result in a state 12 situation.
