Hi!,

I am new raid. I need help to modify raid5.

production server details

Hp ProLiant DL380 G5

total 7 HDD of 146GB

OS - Centos 5

My current setup is as follows,

Array A
unused space : 349956 MB

logical drive :1
total size 273GB
raid5
disk : /dev/cciss/c0d0

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

unassigned disk

1I:1:6
1I:1:7

now what I want to do is -

I want to modify the Array A to use all unused space whithout lossing any data on production server.

I have installed hpacucli cmd. can I use the following command to modify it?

hpacucli ctrl slot=1 logicaldrive 1 modify size=max

do you need to run any other commands?

& how can I add unassigned disk to the same Array A?

Thanks in advance for help. :)
