X4100 Bios RAID question
Hi there
the Sunfire X4100 has a great tool that you can get to from BIOS called the configuration utility which allows you to set up Disk mirroring (RAID 1) before the OS sees it, which is great and it works a treat, however, we have a large datacentre across multiuple sites and I need to find out if there is a way remotely that I can check if a disk has failed and switched over to the mirror or indeed just to confirm the mirror is up and stable and everything is ok? ...obviously it is not feasible to visit each machine with a monitor and keyboard then reboot it, just to check if all is OK
I know IPMI tool is used to probe hardware on x86 boxes and maybe this is what I could use? but thats just a guess
Does anybody know how I can proactively monitor the mirroring situation of these boxes remotely? the Sun documentation for these boxes gives no indication of a command line utility to check this stuff
Any help would be greatly appreciated
Cheers

Hi
Can I add disks on the fly to extend the capacity of an existing RAID 5 volume?
It's created on a 4P Advanced SSA Raid Adapter.
I need to extend a volume group, so I figured it would be easiest to extend the "physical disk" which is a RAID5 volume.
Thanks. (1 Reply)

Hi everyone
I've just purchased a Sun T5120 server with 2 internal disks. I've configured hardware RAID (mirror) and as a result the device tree in Solaris only contains 1 hard drive.
My question is, how would I know when one of the drives become faulty?

ataraid
ATARAID(4) BSD Kernel Interfaces Manual ATARAID(4)
NAME
ataraid -- software BIOS RAID
SYNOPSIS
pseudo-device ataraid
ld* at ataraid? vendtype ? unit ?
DESCRIPTION
The ataraid driver provides support for BIOS-based software RAID controllers. These are devices which have some simple support for several
basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function. The BIOS support is
largely just to create and recognize the array so that it may be a boot device.
The driver currently supports RAID formats from:
o Adaptec HostRAID (found in Intel 6300ESB)
o Intel MatrixRAID
o JMicron RAID
o nVidia MediaShield
o Promise FastTrak
o Via V-RAID (found in many VIA-based motherboards)
Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility.
SEE ALSO
ld(4), bioctl(8)
HISTORY
The ataraid driver first appeared in NetBSD 2.0.
AUTHORS
The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>.
BUGS
Not all features of the software RAID are currently recognized or supported. For example, the Adaptec support doesn't recognize when a RAID
1 should be in a ``building'' state, and it does not do the right thing.
At least part of the reason for this is that the publically-available information on these formats is quite limited.
