Existed HDD expend size (extand) On ESXi
1. modify HDD Size
On OS
2. check host#
# ls /sys/class/scsi_host
3. scan host#
ll /sys/class/scsi_disk
echo "- - -" > /sys/class/scsi_host/host#/scan
ls /sys/class/scsi_disk
echo "1" > /sys/class/scsi_disk/0\:0\:1\:0/device/rescan ;
scsi lihat di VM
4. check target HDD
fdisk -l
5. resize
resize2fs /dev/sd? ( or resize4fs )
resize2fs -f ( force /paksa )
6. mount -a
Add HDD to GuestVM On OS
01. Check host#
# ls /sys/class/scsi_host
02. Scan host
echo
"- - -" > /sys/class/scsi_host/host1/scan
echo "- - -" > /sys/class/scsi_host/host2/scan
echo "- - -" > /sys/class/scsi_host/host3/scan
03. fdisk : check new HDD ID,
ex : /dev/sdb, /dev/sdc
fdisk -l
04. mkfs: format HDD
mkfs -t ext4 /dev/sd?
05. mount to target
mount /dev/sd? /target_folder_name
06. (For Oracle) modify folder owder
chmoe /target_folder_name
07. check hdd ID
blkid
08. Modify /etc/fstab : Auto mount HDD when system on
mount -a
09. Check Disk
df -h
