326 HP StorageWorks Disk Array XP RAID Manager: User’s Guide
Using RAID Manager in HA environments
When using HA software (such as MC/ServiceGuard or Cluster Extension
XP), application packages can be transferred to the takeover host node at
any time. If the application package transfer operation is performed in an
environment where CA is used, you may need to switch the CA secondary
volumes to primary volumes. The
horctakeover command provides this
function.
The horctakeover command provides macro functions to determine the
data consistency of the S-VOL and to perform these takeover functions:
takeover-switch
swap-takeover
SVOL-takeover
PVOL-takeover
The horctakeover command is not available for BC.
HA control script state transitions
The table on page 315 lists volume states and state transitions resulting
from the execution of either
pairvolchk or horctakeover in HA control
scripts from either Data Center 1 (DC1) or Data Center 2 (DC2).
When a HA failover/failback control script is activated, it will:
retrieve the state of the CA paired volume accessible to the local host
(via
pairvolchk –s)
retrieve the state of the remote side of the pair (via pairvolchk –s –c)
select the proper action (for example, failover, failback, ask for
operator intervention, etc.)
