What is the procedure for replacing 18gig drives with 73gig drives in a JBO which is mirrored on a UNIX system?
Posted on 2004-10-19
I have a UNIX High Availability system in which the JBOD hold a database for our application (hospital patient demographics database) and the system is due for an upgrade. The upgrade mandates larger drives of which I have 6 each 73gig drives that will replace the 6 18gig drives presently in use. I know that there is a need to halt the system, break the mirror, transfer the data to another storage device (dds tape or raid) and then pull the drives, replace them, reload data and then remirror the 6 drives. I also am aware that there are some unmouts / mounts and logical volumn management that has to happen. The logical volume that I will have to concern myself with is a vgwise and I add this only in allowing anyone responding the opportunity to use a label within their explanation. Thanks much.
