I am new to raid array & want to extend existing raid 5.
I need help to extend array.the current setup is as follows,

Array A
unused space : 349956 MB

logical drive :1
total size 273GB
disk : /dev/cciss/c0d0

1I:1:5 - 146gb
2I:1:1 - 146gb
2I:1:2 - 146gb
2I:1:3 - 146gb
2I:1:4 - 146gb

now I want to use unused space. How can I extend the array using unused space?

another thing I have 2 more unassigned disk.

if I want to use that too, how I can extend the existing array?
I dont want to loose any data. server is in production.
so I want to use "hpacucli" command.

all help appreciate.

Sounds like an HP RAID controller? HP server as well? Which ones? The OS - Linux?

Did you see this tutorial?

Have you tried running an HP ACU GUI version? (That would make array expansion a no-brainer.)
