Ive also had the following in the event log.. (not at the same time) Application popup: Windows - Delayed Write Failed : Windows was unable to save all the data for the file \Device\HarddiskVolume23\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. How do I find volume23?? No drives are showing errors.. the array appears healthy.. and ACU shows nothing.. neither does secure path etc.. ideas?? I may have to try a reboot.. :o on a cluster :rolleyes: David |
Check the state of your FC HBAs on the server. Are you using multipathing ? If so, if you have one flaky HBA it shouldnt make a difference. If not then you could have a flaky HBA causing problems.
Check your SAN (dunno if Compaq/HP use Brocade/Macdata/Gadzoox/whatever) switches, but use the tools (command line or web based) to check the health of the SAN. Could throw up a cable or HBA error. I guess youve checked the media, drive for errors. Theres not alot to check on the FC/SCSI bridges (we used ADIC/IBM badged ones), again the config tools via the serial port is a start. Once you have established the hardware is good, then you know where you stand. Edit - do backups go over the SAN direct, or via a storage node over the LAN ?

backup via a node..
fairly sure the HBA's are Ok.. I may manually fail them over mid backup.. David |
cough
|
Have you looked for network problems ? Try the switch logs and see if theres a clue in the times in there.
|
Nothing both FC switches look fine and dont have anything showing in them..
Im going into work tonight so may rebooting everything including the switches. |
Rebooting the cluster is a good idea as on boot the server will display any disk failures or problem which is what I believe it is
Is the quorum resource on a separate disk to the other data volumes , if not it should be. Cheers TONY |
my insight server has died so rebuilding that...
However, it seems that I may have to power the MSL up, then The MDR then the san nodes... I think its a disk failure too.. :o I am doing it a 22:00 tonight.. :eek: trying to find information on configuring the MDR etc... and not finding much.. David |
tried ringing HP support Dave? don't you get 3 year warranty with that stuff?
|
