Pl find the below command ,
In the above output , i want to know how this RAID 1 volume has been created , whether it is created of two disks or three disks as because i find in "raidctl -l " command there are three disks present .
And also i want to do the patching on this server , any one tell me how to split this raid 1 volume and do the activity.
I don't understood why on SPARC-Platforms have not present RAID-Controller ? Sorry for my bad english, but it's crazy always setup software RAID !!! I whanna Hardware RAID and when i can find solution ? (7 Replies)
We have a Red Hat linux server running on IBM x445 hardware. There are external disks in an IBM EXP300 disk enclosure. The system is running RAID 5. One of the four IBM disks (73.4 GB 10k FRU 06P5760) has become faulty. The system is still up and running OK because of the RAID. In that same EXP300... (3 Replies)
Hi.
I need to move a 5 disk RAID5 array from a SE3310 box to a different SE3310 array. After installing the disks in the "new" StorEdge device, I "would like" ;) to be able have access to the data which is on the RAID.
Essentially, the quesion is, how can this be done? :confused:
I checked... (5 Replies)
I've just installed Sol 10 Update 9 on a Sun 4140 server and have a RAID 1 configuration (2 136 Gb drives) for the OS and have created a RAID 5 array (6 136 GB) drives. When i log into the system I am unable to see the RAID 5 disks at all. I've tried using the devfsadm command but no luck and... (9 Replies)
Hello,
I have a scsi pci x raid controller card on which I had created a disk array of 3 disks
when I type lspv ; I used to see 3 physical disks ( two local disks and one raid 5 disk )
suddenly the raid 5 disk array disappeared ; so the hardware engineer thought the problem was with SCSI... (0 Replies)
Server Model: T5120 with 146G x4 disks.
OS: Solaris 10 - installed on c1t0d0.
Plan to use software raid (veritas volume mgr) on c1t2d0 disk.
After format and label the disk, still not able to detect using vxdiskadm.
Question:
Should I remove the hardware raid on c1t2d0 first?

Hey everyone. First, let me start by saying I'm primarily focused on linux boxes, and just happened to get pulled into building two T5220's. I'm not super educated on sun boxes.
Both T5220's have 8 146GB 15k SAS drives. Inside the service processor, I can run SHOW /SYS/HDD{0-7} and they all come... (2 Replies)

MFI(4) BSD Kernel Interfaces Manual MFI(4)NAME
mfi -- LSI MegaRAID SAS driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device pci
device mfi
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
mfi_load="YES"
DESCRIPTION
This driver is for LSI's next generation PCI Express SAS RAID controllers. Access to RAID arrays (logical disks) from this driver is pro-
vided via /dev/mfid? device nodes. A simple management interface is also provided on a per-controller basis via the /dev/mfi? device node.
The mfi name is derived from the phrase "MegaRAID Firmware Interface", which is substantially different than the old "MegaRAID" interface and
thus requires a new driver. Older SCSI and SATA MegaRAID cards are supported by amr(4) and will not work with this driver.
Two sysctls are provided to tune the mfi driver's behavior when a request is made to remove a mounted volume. By default the driver will
disallow any requests to remove a mounted volume. If the sysctl dev.mfi.%d.delete_busy_volumes is set to 1, then the driver will allow
mounted volumes to be removed.
HARDWARE
The mfi driver supports the following hardware:
o LSI MegaRAID SAS 1078
o LSI MegaRAID SAS 8408E
o LSI MegaRAID SAS 8480E
o LSI MegaRAID SAS 9260
o Dell PERC5
o Dell PERC6
o IBM ServeRAID M5015 SAS/SATA
o IBM ServeRAID-MR10i
o Intel RAID Controller SROMBSAS18E
FILES
/dev/mfid? array/logical disk interface
/dev/mfi? management interface
DIAGNOSTICS
mfid%d: Unable to delete busy device An attempt was made to remove a mounted volume.
SEE ALSO amr(4), pci(4), mfiutil(8)HISTORY
The mfi driver first appeared in FreeBSD 6.1.
AUTHORS
The mfi driver and this manual page were written by Scott Long <scottl@FreeBSD.org>.
BUGS
The driver does not support big-endian architectures at this time.
