#Sas drive software#

The operating system in question is RHEL5.3: ~]# cat /etc/redhat-release But for next time, how can I make Linux recognize a new SATA drive I have hot swapped in without rebooting?

#Sas drive software#

dev/sda was recognized, I fixed the software RAID, and everything is fine now. bash: echo: write error: Invalid ~]# /root/rescan-scsi-bus.sh -l

I tried a couple things to make the server find the new /dev/sda, such as rescan-scsi-bus.sh but they didn't work: ~]# echo '-' > /sys/class/scsi_host/host0/scan May 5 16:55:45 fs-2 kernel: ata1: EH complete May 5 16:55:45 fs-2 kernel: ata1: reset failed, giving up May 5 16:55:40 fs-2 kernel: ata1: soft resetting link May 5 16:55:40 fs-2 kernel: ata1: limiting SATA link speed to 1.5 Gbps May 5 16:55:10 fs-2 kernel: ata1: link is slow to respond, please be patient (ready=0) May 5 16:55:05 fs-2 kernel: ata1: soft resetting link May 5 16:55:00 fs-2 kernel: ata1: link is slow to respond, please be patient (ready=0) May 5 16:54:55 fs-2 kernel: ata1: soft resetting link
