The following table lists and describes the HORCM system log messages and
provides recommended actions for resolving the error conditions.

(secondary) volumes. Alternate path using Path Manager (Safe
Path) is limited to primary volumes.
When executing horctakeover on a standby server manually, I/O
on the active server must be stopped. When the package software
goes for a standby server a failover by HA software, the HA
software must guarantee an I/O insulation of the active server.
After a new system has been constructed, a failure to activate
HORCM might occur due to improper environment setting and/or
configuration definition. Refer to the HORCM activation log, and
correct the settings.
Refer to the command log file and HORCM log file to identify the
cause of the error. If a command terminates abnormally because of
a remote server failure, recover the server from the failure, then re-
execute the command. If HORCM has shut down, restart HORCM. If
an unrecoverable error occurs, obtain the log files and contact
Hitachi Data Systems customer support.
TrueCopy only: If an error occurs in duplicated writing in paired
volumes (that is, pair suspension), the server software using the
volumes might detect the error by means of the fence level of the
paired volume. In such a case, check the error notification
command or syslog file to identify a failed paired volume.
The system administrator can confirm that duplicated writing in a
paired volume is suspended due to a failure and the system runs in
regressed state using the error notification command of the
TrueCopy. HORCM monitors failures in paired volumes at regular
intervals. When it detects a failure, it outputs it to the host's syslog
file. Thus, the system administrator can detect the failure by
checking the syslog file. Concerning the operation of the RAID
storage system, the failure can also be found on Storage Navigator
(or SVP) provided.
Issue the TrueCopy commands manually to the identified failed
paired volume to try to recover it. If the secondary volume is
proved to be the failed volume, issue the pair resynchronization
command to recover it. If the primary volume fails, delete the
paired volume (pair splitting simplex) and use the secondary
volume as the substitute volume.
CCI uses "/HORCM/.uds" as the directory for the UNIX domain
socket for IPC (Inter Process Communication), and makes the
directory and files as "/HORCM/.uds/.lcm*" in CCI version
01-17-03/01 or later.
Caution: This "/HORCM/.uds/.lcm*" should not be removed while
HORCM is running.
