While adding a new disk to an ESX5.5. box it could not finish the partitioning stage and did not add to the Datastores.

Apparently ESX does succeed to clean up the Disk from the GUI.

NOTE: This procedure will destroy all data on the disk

Suppose the Disk is /dev/sdb, the second scsi disk,

   fdisk /dev/sdb

   create as many partitions as you need using command n

   Label them with command t as 8e for making it Linux LVM

   Write and Exit with the command w.

Format the partitions you require using mkfs command

   mkfs -t ext3 -c /dev/sdb1

LVM commands

   pvcreate /dev/sdb1

   vgextend VolGroup00 /dev/sdb1

   lvextend -L 15G /dev/VolGroup00/LogVol01 ;for extending LogVol to 15GB

   lvextend -L+1G /dev/VolGroup00/LogVol01 ;for adding one more GB to Logical Volume LogVol01

   lvextend -l +100%FREE /dev/VolGroup00/LogVol01

Next you shall need to resize the filesystem.

   resize2fs -l /dev/VolGroup00/LogVol01

Thats it finished Njoy 🙂 !
