Note: It is a very good idea to do a backup before performing these steps. Just ins case.

Step 1 - Prerequisites

  1. UCS-System installed at UEFI running on an hypervisor
  2. Through the hypervisor the disk is already enlarged
  3. scsi_reschan.sh (209 Bytes) has been run to update disks (optional partprobe or reboot)

Step 2 - Fix errors in partition table

when starting cgdisk some errors will appear. Ignore them.
cgdisk /dev/sda
Press “w” to write the (now fixed) partition table.
Press “q” to quit cdisk.

Step 3 - Star cgdisk again

cgdisk /dev/sda
Delete the UCS partition and re-create with the same starting sector as before. Match the new size.
Press “w” to write the (now resized) partition table.
Press “q” to quit cdisk.

Step 4 - Reboot

shutdown -r now
