Options
(continued)
-l: Enables read and write to the primary volumes by a local host only without
a remote host, and executes PVOL-takeover when the primary volume cannot
be used because it is fenced (fence = DATA, state = PSUE, or PSUE volume is
contained in the group). If the primary volume can be accessed, nop- takeover
is executed. The target volume of the local host must be a P-VOL.
-t<timeout>:
Must be specified for async volumes only (TCE), ignored for
sync. Specifies the maximum time to wait (in seconds) for swap-takeover and
SVOL-takeover operation to synchronize the P-VOL and S-VOL. If this timeout
occurs, the horctakeover command fails with EX_EWSTOT. To avoid timeout,
set this value less than or equal to the start-up timeout value of the HA Control
Script.
-nomsg: Suppresses messages to be displayed when this command is
executed. It is used to execute a command from a user program. This option
must be specified at the beginning of a command argument. The command
execution log is not affected by this option.
Returned
values
Normal termination:
0: Nop-takeover (no operation).
1: Swap-takeover was successfully executed.
2: SVOL-takeover was successfully executed.
3: PVOL-SMPL-takeover was successfully executed.
4: PVOL-PSUE-takeover was successfully executed.
5: SVOL-SSUS-takeover was successfully executed.
Abnormal termination:
other than 0-5, Returns a common error code and a
unique error code for this command. For details on error codes, see
Table 1-15: Horctakeover Command Parameters (Continued)
Parameter
Value
NOTE: During TrueCopy or TCE pair operation, there are cases where pair
operation fail when high volume host I/O or frequent change of pair status
is occurring on both local and remote array. If pair operation fails and state
transition is not done, then retry the pair operation (pairvolchk command
can be used to check the state transition). When some of the pair operators
fail, it is required to perform the pair operation for each logical volume pair
in the group.
