Today I added 1GB of extra space to a virtual disk (basically extended it) in esxi VM. I followed 2 approaches to get the new space recognized:
echo "- - -" > /sys/class/scsi_host/host2/scanecho 1 > /sys/class/scsi_disk/2:0:1:0/device/rescanFirst approach din't work, second one worked.
Any thoughts?
I haven't read documentation in the kernel source tree, that might have what I want.
As "val0x00ff" shared the link containing exact answer already:

Once you've changed the disk's size in VMware and did not reboot your server, rescan your SCSI devices as such. First, check the name(s) of your scsi devices.
$ ls /sys/class/scsi_device/
Then rescan the scsi bus. Below you can replace the '0:0:0:0′ with the actual scsi bus name found with the previous command. Each colon is prefixed with a slash, which is what makes it look weird.
$ echo 1 > /sys/class/scsi_device/0:0:0:0/device/rescan
That will rescan the current scsi bus and the disk size that has changed will show up.
