FRU error during VDISK expansion

I've recieved the following error during a VDISK expansion operation:

There is a problem with a FRU. (FRU type: disk, enclosure: 1, device ID: 6, vendor: ATA , product ID: ST32000644NS , SN: 9WM12MFA, version: AN11, related event serial number: A67966, related event code: 55)

The expansion seems to be continuing despite the error - albeit VERY slowly.

According to the MSA Event Description Reference Guide:

55
Warning The indicated disk reported a SMART event.
A SMART event indicates impending disk failure.

QUESTION: Can a problematic disk be replaced during a VDISK expansion operation?
