hard disk failure in experion pks message summary

we have many experion pks servers in ower factory, (2 redundant servers in each area) each servers have four SCSI hard disks configured in raid 5.

after more five years of working, we have frequently hard disks failure that need to be replaced to maintain servers working. my question is how can I do to configure an alarm to be displayed in message summary of Epks each time when a hard disk fail?

thanks
