I tried to resize a logical volume but showed a message to specify stripes and stripesize

root@linux:~ # lvresize -L +200g -r /dev/vgER0data/lv_sapdata1
Please specify number of stripes (-i) and stripesize (-I)
Run `lvresize –help’ for more information.

Showing stripes and stripesize

root@linux:~ # lvdisplay /dev/vgER0data/lv_sapdata1 -m
— Logical volume —
LV Path /dev/vgER0data/lv_sapdata1
LV Name lv_sapdata1
VG Name vgER0data

— Segments —
Logical extents 0 to 655359:
Type striped
Stripes 2
Stripe size 4.00 MiB
Stripe 0:
Physical volume /dev/mapper/ER0_data_disk_001p1
Physical extents 0 to 327679
Stripe 1:
Physical volume /dev/mapper/ER0_data_disk_002p1
Physical extents 0 to 327679

Logical extents 655360 to 783354:
Type linear
Physical volume /dev/mapper/ER0_data_disk_003
Physical extents 0 to 127994

To solve the problem in this case it was necessary to add a new LUN and resize the logical volume. The segment where it is linear, was kept this way. There is no way to convert

root@linux:~ # lvresize -L +100g -r -i2 -I4M /dev/mapper/vgER0data-lv_sapdata1
Size of logical volume vgER0data/lv_sapdata1 changed from 2.99 TiB (783355 extents) to 3.09 TiB (808955 extents).
