Added new hard drive to IBM Xseries but not seeing space increases

Added new hard drive to IBM Xseries but not seeing space increases

Added new hard drive to IBM Xseries but not seeing space increases


I added a new hard drive to the existing RAID 5 on a IBM xseries 346 server.  I used ServerRAID management to add the new drive to the logical volume pool.  I see the migrating process is going, then I restarted the server.
I then check the size after the server booted up and seeing the size has not increased.  The new hard drive I added to the server are same model as those already in the server and the new drive blinking green light.  I am using RedHat 5, and not sure if I need to do anything on the OS to see the new size?

Please help!!!


RE: Added new hard drive to IBM Xseries but not seeing space increases

what you have done is correct, but not enough.

Go in Windows Disk Management: how many disks do you see ?
Is this RAID5 the unique volume in server ? (contains C: partition)

In the disk you'll se a zone (at the end) not partitioned.

If the raid5 does not contain C part, it's easy:
use diskpart (see well doc) and "extend" partition.

If it contains C: partition, conceptually is the same,
but you cannot do this on a mounted partition:
you have to boot from a CD, with inside tools to extend partitions. You can use BartPE or others.
