HSZ80 problem

Daniel Fernandez Illan — Wed, 01 Jun 2005 03:46:05 GMT

Hi all
I have two HSG80 controllers configured for dual redundancy. One of them doesn´t restart (I think that is a failure of array controller). Characteristics of controller that work are:
Controller:
HSZ80 ZG93301356 Software V83Z-0, Hardware E04
NODE_ID = 5000-1FE1-0002-6B60
ALLOCATION_CLASS = 0
SCSI_VERSION = SCSI-2
Configured for dual-redundancy with ZG93300847
In dual-redundant configuration -- other controller restarting
Device Port SCSI address 7
Time: NOT SET
Host PORT_1:
SCSI target(s) (0, 1, 2, 3)
No preferred targets
TRANSFER_RATE_REQUESTED = 20MHZ
Host Functionality Mode = A
Command Console LUN is target 0, lun 5
Host PORT_2:
No SCSI targets
No preferred targets
TRANSFER_RATE_REQUESTED = 20MHZ
Cache:
128 megabyte write cache, version unknown
Cache is GOOD
No unflushed data in cache
CACHE_FLUSH_TIMER = DEFAULT (10 seconds)
Mirrored Cache:
128 megabyte write cache, version unknown
Cache is GOOD
No unflushed data in cache
Battery:
FULLY CHARGED
Expires: 14-OCT-2005
NOCACHE_UPS
Extended information:
Terminal speed 9600 baud, eight bit, no parity, 1 stop bit
Operation control: 00000000 Security state code: 62478
Configuration backup disabled

(yes, firmware version is very older, but...)
My question:
There is some procedure to permit works with only one controller and use two array disk?)

Thanks in advance
Saludos.
Daniel

You can unbind the controllers with the "SET NOFAILOVER" command and you can disconnect the second cache module with the "SET THIS_CONTROLLER NOMIRROR..." command.

Thanks Uwe
I executed SET NOFAILOVER in controller that is working, but my problem is obtain a procedure to start the other bad controller. When I execute FRUTIL send me a message indicating that the other controller isn't shutdowned and return to hsg prompt.
Also bad controller send to console a failure message <> with:

last failure code 02ef0102
LPP(0) 0000002e
LPP(1) 00000000

I don't know a command restart bad controller or permit to see disks for first HSG80.

Some suggestion?
Daniel.

Hi
The problem is solved.
I had installed other controller, and after reinstall and restart it, appears a message about cache isn't properly instaled to this controller, but propmt of controller is accesible.
Before reinstall configuration on this controller it is needed to clear invalid cache information using:

clear_errors this_controller invalid_cache DESTROY_UNFLUSHED_DATA
It is important to use DESTROY option because the problem with controller (recursive bugcheck) was a bud information in cache.

Thanks Uwe
Saludos.
Daniel.
