In these cases, the affected ACS(s) is forced offline. The HSC continues to support the unaffected ACS(s).

While the unaffected ACS(s) remains online, the mismatched configuration can be corrected. If the hardware configuration is incorrect, the affected ACS(s) can then be brought online. Otherwise, the configuration can be changed through the LIBGEN/SLICREAT/Reconfiguration process at your convenience.

Multiple Hosts Startup Considerations

In a multiple-host configuration, start one host at a time. Do not bring up multiple hosts simultaneously.
