Hi,

At job we have an HP Proliant DL380 G4 High Performance with a RAID 5
array with 4 SCSI disks with 36.4 Gb capacity each one.

Last week one disk failed and the RAID 5 is working without one disk.
My problem and doubt is that HP is not selling anymore 36.4Gb disks,
just 72Gb or 142 Gb disks. My question is: What happen if I change the
disk falied and I replace with a 72 Gb one?

It works fine, I've done it many times on HP systems.
