If I execute the following command:
Code:
echo "- - -" > /sys/class/scsi_host/host<X>/scan
Can the scan kick out a disk that might fail?
I'm running raid10 and a disk broke, when I tried replacing the new the disk I got the following:
Code:
end_device-4:9: mptsas: ioc0: removing ssp device: fw_channel 0, fw_id 3, phy 3,sas_addr 0x5000c5003a458475
phy-4:3: mptsas: ioc0: delete phy 3, phy-obj (0xffff88041e9d3c00)
port-4:9: mptsas: ioc0: delete port 9, sas_addr (0x5000c5003a458475)
mptsas: ioc0: attaching ssp device: fw_channel 0, fw_id 3, phy 3, sas_addr 0x5000c5007421ede9
scsi target4:0:10: mptsas: ioc0: delete device: fw_channel 0, fw_id 3, phy 3, sas_addr 0x5000c5007421ede9
and a smartctl -i gives the following:
Code:
smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.2.0-4-amd64] (local build)

Smartctl open device: /dev/sde failed: No such device
Previously, I was able to echo and rescan the disk no problem. My worry here is that another disk looks like it's about to fail:

Could running the above command scan and kick sdc? I don't want sdc to be kicked because it will cause my server to crash.
Any help is appreciated!
