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)

bioctl
BIOCTL(8) BSD System Manager's Manual BIOCTL(8)NAME
bioctl -- RAID management interface
SYNOPSIS
bioctl device command [arg [...]]
DESCRIPTION
RAID device drivers which support management functionality can register their services with the bio(4) driver. bioctl then can be used to
manage the RAID controller's properties.
COMMANDS
The following commands are supported:
show [disks | volumes]
Without any argument by default bioctl will show information about all volumes and the logical disks used on them. If
disks is specified, only information about physical disks will be shown. If volumes is specified, only information about
the volumes will be shown.
alarm [disable | enable | silence | test]
Control the RAID card's alarm functionality, if supported. By default if no argument is specified, its current state
will be shown. Optionally the disable, enable, silence, or test arguments may be specified to enable, disable, silence,
or test the RAID card's alarm.
blink start channel:target.lun | stop channel:target.lun
Instruct the device at channel:target.lun to start or cease blinking, if there's ses(4) support in the enclosure.
hotspare add channel:target.lun | remove channel:target.lun
Create or remove a hot-spare drive at location channel:target.lun.
passthru add DISKID channel:target.lun | remove channel:target.lun
Create or remove a pass-through device. The DISKID argument specifies the disk that will be used for the new device, and
it will be created at the location channel:target.lun. NOTE: Removing a pass-through device that has a mounted filesys-
tem will lead to undefined behaviour.
check start VOLID | stop VOLID
Start or stop consistency volume check in the volume with index VOLID. NOTE: Not many RAID controllers support this fea-
ture.
create volume VOLID DISKIDs [SIZE] STRIPE RAID_LEVEL channel:target.lun
Create a volume at index VOLID. The DISKIDs argument will specify the first and last disk, i.e.: 0-3 will use the disks
0, 1, 2, and 3. The SIZE argument is optional and may be specified if not all available disk space is wanted (also
dependent of the RAID_LEVEL). The volume will have a stripe size defined in the STRIPE argument and it will be located
at channel:target.lun.
remove volume VOLID channel:target.lun
Remove a volume at index VOLID and located at channel:target.lun. NOTE: Removing a RAID volume that has a mounted
filesystem will lead to undefined behaviour.
EXAMPLES
The following command, executed from the command line, shows the status of the volumes and its logical disks on the RAID controller:
$ bioctl arcmsr0 show

To create a RAID 5 volume on the SCSI 0:15.0 location on the disks 0, 1, 2, and 3, with stripe size of 64Kb on the first volume ID, using all
available free space on the disks:
$ bioctl arcmsr0 create volume 0 0-3 64 5 0:15.0
To remove the volume 0 previously created at the SCSI 0:15.0 location:
$ bioctl arcmsr0 remove volume 0 0:15.0
