We 've the following config: Compaq DL580G2 HP Netraid-2M HP DS2100 with 4 HDD 36GB 10Krpm
The 4 HDD are configured in two RAID-1 array
The system has been working fine since recently. The system has been rebooted and since then each time it reboots a different HDD ( sometimes more than one ) is taken offline.
The first actions taken includes: - DS2100 substitution. - Failed HDD substitution - Update of DL580 BIOS, Netraid FW - netraid replacement.
It seems somteing related with SCSI timing or similar. We found the following: - Booting the server - a "disk not reponding" error is shown by the Netraid controller. - with CTRL_M we access the netraid conf utility. - we pull-out the non responding disk from the ds2100. - we insert it back and perform a physical disk discovery . - The disk is found and we can take it online.
