RAID Volume in Linux
I am new to Linux and facing a problem. I have a DL580 G3 with Linux AS4 on it. I don't know what RAID is configured and either it is a software RAID or a hardware RAID. There is however HP Smart Array present on the server which has an MSA connected to the server. I don't have any info about the volumes on that MSA and 1 of the disks in the MSA has failed. I have worked a lot with RAID volumes in Windows. Is there any ACU for Linux I don't even know how to check if it is installed or not. So you can imagine how much help i need out here. Can I just pull out the failed disk and put in the new one and will it start rebuild itself? Is there any limitation for different operating systems for this procedure?

In this case, no software RAID is present. The hpacucli package (part of proliant support pack), provides the hpacucli command, to check the smart array configuration, for example:

Probably yes but until you get the ouput of hpacucli we can't be sure.

Re: RAID Volume in Linux
I replaced the disk and the rebuild started but it is showing failed at the MSA500 G2 controller. Do I have to install ACU for Linux or is there any other way that I can find out at how much percent it failed.

Re: RAID Volume in Linux
I hope I can find help on this forum. First, sorry for my English.
I am new to Linux and I have a Proliant DL180 G5 with Centos 5.2 on it.
I have 2 Sata HDD on it, raid 1, hardware.
When I make a rebuild (from Bios) I have to wait 180-240 minutes. Tell me please how can I make the rebuilding from Linux, because the downtime from bios rebuilding si very high. I don't know what raid controller I have (Smart Array E200 or Embbeded Sata). How can I find?
I try to install hpacucli with some steps from forums and I got this:
hpacucli
HP Array Configuration Utility CLI 7.70-12.0
Detecting Controllers...Done.
Type "help" for a list of supported commands.
Type "exit" to close the console.
=> ctrl all show config detail
Error: No controllers detected.
Please help me.
Thank you.
Radu
