We have RHEL 5.8 on a VM in our production environment which is connected to Fujitsu SAN storage. The size of the partitions on RHEL machine has to be increased. We already added a disk to the VM but this has to be visible on the RHEL machine. I am not sure with the commands to rescan, the initial step has to be:
echo "- - -" > /sys/class/scsi_host/host#/scan
Subsequently, to see the disk nomenclature, are the different options:
1) fdisk -l
tail -f /var/log/message
2) dmesg
3) ls –ltrh /sys/block to see the new device
I am not sure of which approach to take from above 3 options or is there something else.
I hope, I have been able to explain the problem.
Requesting a reply to my query.
Regards
