Hi,
Anyone know how I can remove the INVALID Cache on the HSZ50 ?
I could not remove the INVALID Cache even when I use the command:
CLEAR_ERRORS INVALID_CACHE THIS_CONTROLLER
It just put me into a reduced mode in the CLI and does not clear the
INVALID Cache. It seems that it is trying to remove D0 lost_data which
is no longer exist in the system as I have already remove all the
storageset.
The Raid 450 was configured previously as dual redundant controller. I
was not able to get the other controller up due to the invalid cache.
Inorder to get the system up, I was forced to run it in a single HSZ50
Controller and reconfigure the raid on hard disk in the Raid 450
temparory.
I could not bring it back to dual redundant controller unless the INVALID
Cache on the Other controller is clear.
Anyone know how I can clear up this mess.
Please help asap. Thanks

| 882.1 | Urgent, need to get it up and running. | ZPOVC::CSNAQS | Tue May 20 1997 06:08 | 24 | |
Hi,
Now I got the working having the same problems of INVALID cache. I was
working on an NT Cluster setup. Initially, I have both Server able to
see the disk on the Raid 450 one at a time. According to the cluster
manual, I need to power off the Raid 450 so that I could boot up both
Server to install cluster. Therefore, I switch off the power supply of
the raid 450. Could it be the cause of this, that the data was not able
to flush to the disk when I power off the Raid 450 ?
Will my installation of cluster be smoothly if I set the cache policy
to B if that is the case that causes the INVALID Cache problems ?
The command that I type should be:
CLEAR_ERRORS THIS_CONTROLLER INVALID_CACHE
But is still does work. The CLI command is set reduced and if I key in
the above command, it will only seee part of the command and complaint
incomplete command.
Any advise and help ?
Thanks

| 882.2 | You need to complete the command | SSDEVO::JACKSON | Jim Jackson, HSx RAID team | Tue May 20 1997 10:58 | 7 |
Your command is incomplete. It needs a fourth keyword. E.g.:
CLEAR_ERRORS THIS_CONTROLLER INVALID_CACHE DESTROY_UNFLUSHED_DATA
Issuing a question mark would have given you a list of the possible keywords:
CLEAR_ERRORS THIS_CONTROLLER INVALID_CACHE ?
