In N+M cold standby using HCSM, HCSM monitors if the
OS on the standby server blade starts up within the
maximum allotted time for "Host OS Startup" specified by
the user after switching server blades.
If the standby OS startup is not completed within the
maximum allotted time for "Host OS Startup" specified by
the user, an error message displays that N+M failover
failed. (KASV00212-E) is shown on the HCSM task result
window regardless of whether the standby OS has started.
Thus, even if N+M cold standby failover is successful and
the standby OS has started, the error message
(KASV00212-E) may be displayed on the HCSM task
result window.
Standby OS startup completion takes longer on some
types of server blade configuration such as CB 540A blade.
Set an appropriate time for the maximum allotted time for
"Host OS Startup".
