Complete output of SHOW THIS FULL at the HSZ40 at bottom of message
Hello Admin wizards,
after almost two years of painless work we suffered from a power failure
last morning.
Even though we have a UPS connected the system did not power down
regularly as it was supposed to do after the 15 minutes period. So what
I have now is the following problem:
The server itself boots up normally, but does not find the connected HSZ
40 (dual redundant) controllers, better: the defined raidsets, formerly
known as HSZ40#raid -> /dev/rrz17g and so on. I already figured that the
symlinks in /etc/fdmns are missing; I recreated them by unpacking the
fdmns dir from a tarfile, but no success. Am I supposed to do a MAKEDEV
in /dev/ again?
Having connected the laptop to the device, one of them says
--------------------------------------------------
This controller has an invalid cache module
Controllers misconfigured. Type SHOW THIS_CONTROLLER
Power Supply failure cleared.
Invalid cache -- CLI command set reduced. Type SHOW THIS_CONTROLLER.
Please-
see user guide to determine corrective action
--------------------------------------------------
The other one seems to be ok, and it shows the raids and units as it is
supposed to be.
The user guide suggests to use the command
CLEAR_ERRORS INVALID_CACHE THIS_CONTROLLER
but the device responds with
HSZ_UNTEN > CLEAR_ERRO
Incomplete command
it wont accept complete commands but breaks after an unpredictable
length. Same if I try to issue SET FAILOVER COPY=OTHER - breaks after
SET FAILO and complains about incomplete command ...
I wonder why, and how I can get out of this mess ....
would be grateful for any hint
regards
CW
