NOTE:
For Fibre Channel interface, do not use the CESTPATH and CDELPATH commands at the
same time as the SCSI path definition function of LUN Management. The Fibre Channel interface
ports need to be configured as initiator ports or RCU target ports before the CESTPATH and
CDELPATH commands are issued.
6.
If you plan to use the same channel extenders, change the operating mode back to the original
direction. The boxes/nodes connected to the MCUs must be set to channel-mode and the boxes/nodes
connected to the RCUs must be set to device-mode.
7.
At the main site, configure the RCPs or initiator ports, add the RCUs, and add the TC390A groups. If
SVP mode 114 is enabled on all MCUs and RCUs, the ports will reconfigure automatically if you use
the TSO CESTPATH command to add the pairs at the main site.
CAUTION:
Before issuing the CESTPATH command, verify that the relevant paths are offline from
the host(s) (for example, configure the Chipid offline, deactivate the LPAR, or block the port in the
ESCD). If any active logical paths still exist, the add path operation will fail because the port mode
(LCP/RCP) cannot be changed.
8.
At the main site, establish all TC390A groups and TC390 pairs in the original direction. You may use
the No Copy initial copy option because all M-VOLs and R-VOLs are synchronized. If there is any
possibility that the volumes are not 100% synchronized, use the Entire initial copy option to be safe.
9.
Vary the MCU and M-VOLs online and start the applications at the main site.
Troubleshooting
General TrueCopy Troubleshooting
In the unlikely event of a problem with the Command View XP management station or Command View XP
or XP Remote Web Console software, first verify that the problem is not being caused by the PC or Ethernet
hardware or software, and then try restarting the PC. Restarting the Command View XP management
station does not affect TC390 operations already in progress. For a description of the TC390 error
messages displayed on the Command View XP management station or XP Remote Web Console, see
NOTE:
Use the FDCOPY function to copy the Command View XP or XP Remote Web Console
configuration information onto diskette and give the diskette(s) to HP service personnel.
