Cannot allocate more space to Logical Volume in SAP CAL

Hello Experts,

I am struggling in allocating additional space on the logical volume vgcal/sysfiles inside an IDES ERP 6.0 including Enhancement Pakcage 7 on SAP HANA solution instance

We are adding a new physical drive via AWS to the machine, by checking via parted -l it shows up as /dev/xvdt and has 300 GB in total space

I am adding the drive to the Logical Volume manager via

#>pvcreate /dev/xvdt

#>vgextend vgcal /dev/xvdt

the command vgs then shows

#>vgs

  vgcal  13   4   0 wz--n- 839.95g 300.04g

so there is 300 GB free space in the vg

We are stopping SAP system and HANA DB, then I am unmounting vgcal-sysfiles, which is usually mounted in v/vol/vol_ERP/sysfiles, /usr/sap/HDB

/usr/sap/<SID>, /usr/sap/trans, /usr/sap/ccms, /sapmnt/ERP and /hana/shared/HDB

then I try to extend the space of vgcal/sysfiles by 150 GB

#>lvextend -L+150G vgcal/sysfiles

  Using stripesize of last segment 64.00 KiB

  Extending logical volume sysfiles to 298.88 GiB

  Insufficient suitable allocatable extents for logical volume sysfiles: 38388 more required

calculating 38388 extend * the physical Extent Size of 4 MB = there is an additional 150 GB needed.  But even if we add a second device /dev/xdvu with 150 GB of space to the Volume Group, the values stay the same.

Any suggestions why this doesn't work.

Sincere regards
