5.2.13 Reset Configuration and sysWipe
Reset Configuration or sysWipe will delete all LUNs and bring the RAID system to
a default state: active controller A, passive controller B and one default 10-MB LUN
0.
Reset Configuration is a RAID Manager 6 procedure and sysWipe is a serial port
command. sysWipe wipes clean all prior DacStore data. You need to issue a
sysReboot after a sysWipe command is executed.
Caution – Only trained and experienced Sun personnel should access the serial
port. You should have a copy of the latest Debug Guide. There are certain commands
that can destroy customer data or configuration information. No warning messages
appear if a potentially damaging command has been executed.
Note – When you issue a sysWipe command you may see a message indicating
that sysWipe is being done in a background process. Wait for a follow-on message
indicating that sysWipe is completed before issuing a sysReboot command.
sysWipe should be run from each controller.
There are times when a known good controller A is held in reset by controller B so
you will not be able to access the shell tool to issue a sysWipe command for
controller A. In this case, perform the following:
1. Physically remove controller A and controller B.
2. Then insert controller A but leave controller B out temporarily.
3. Issue a sysWipe command followed by a sysReboot command for controller A.
4. Then physically remove controller A and insert controller B.
5. Issue a sysWipe command followed by a sysReboot command for controller B.
6. Then insert controller A back into the system and the system should be in a
default state.
