Hello,
I want to delete a RAID configuration an old server has.
Since i haven't the chance to work with the specific raid controller in the past can you please help me how to perform the configuraiton?
I downloaded IBM ServeRAID Support CD but i wasn't able to configure the video card so i... (0 Replies)
Hi. I have been running OpenBSD(4.9) and it recognizes my Belkin wireless adapter and I don't have issues with it very often. I prefer FreeBSD over OpenBSD, but FreeBSD(7.4) doesnt recognize my USB wifi card. Under OpenBSD ifconfig shows my card as rsu0 so I tried adding the following to... (1 Reply)
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)

Hi ,
I am new into solaris , need to know what a system Controller is , what it exactly does. Is it available in all Sun boxes or only on High end servers.
Is it similar to the Linux console in AIX boxes .
Thanks !!! (7 Replies)
Hi I am trying to format all the disks in several of my old dec-alphas and unix boxes. I have connected to the hsz70 controller and used "run hsutil" command but when i select the "format" option, the response i get is "no available unattached devices to format" Does anyone know how I can...

Hi!!
I am these days working on a project, where I need to know about the disk controllers available in a machine (e.g., 3ware,IBM,etc).
Please, let me know the command by which I can get the information.
thnx,

HPSA(4) Linux Programmer's Manual HPSA(4)NAME
hpsa - HP Smart Array SCSI driver
SYNOPSIS
modprobe hpsa [ hpsa_allow_any=1 ]
DESCRIPTION
hpsa is a SCSI driver for HP Smart Array RAID controllers.
Options
hpsa_allow_any=1: This option allows the driver to attempt to operate on any HP Smart Array hardware RAID controller, even if it is not
explicitly known to the driver. This allows newer hardware to work with older drivers. Typically this is used to allow installation of
operating systems from media that predates the RAID controller, though it may also be used to enable hpsa to drive older controllers that
would normally be handled by the cciss(4) driver. These older boards have not been tested and are not supported with hpsa, and cciss(4)
should still be used for these.
Supported Hardware
The hpsa driver supports the following Smart Array boards:
Smart Array P700M
Smart Array P212
Smart Array P410
Smart Array P410i
Smart Array P411
Smart Array P812
Smart Array P712m
Smart Array P711m
StorageWorks P1210m
Configuration Details
To configure HP Smart Array controllers, use the HP Array Configuration Utility (either hpacuxe(8) or hpacucli(8)) or the Offline ROM-based
Configuration Utility (ORCA) run from the Smart Array's option ROM at boot time.
FILES
Device Nodes
Logical drives are accessed via the SCSI disk driver (sd(4)), tape drives via the SCSI tape driver (st(4)), and the RAID controller via the
SCSI generic driver (sg(4)), with device nodes named /dev/sd*, /dev/st*, and /dev/sg*, respectively.
HPSA-Specific Host Attribute Files in /sys
/sys/class/scsi_host/host*/rescan
This is a write-only attribute. Writing to this attribute will cause the driver to scan for new, changed, or removed devices (e.g,.
hot-plugged tape drives, or newly configured or deleted logical drives, etc.) and notify the SCSI midlayer of any changes detected.
Normally a rescan is triggered automatically by HP's Array Configuration Utility (either the GUI or the command-line variety); thus,
for logical drive changes, the user should not normally have to use this attribute. This attribute may be useful when hot plugging
devices like tape drives, or entire storage boxes containing pre-configured logical drives.
/sys/class/scsi_host/host*/firmware_revision
This attribute contains the firmware version of the Smart Array.
For example:
# cd /sys/class/scsi_host/host4
# cat firmware_revision
7.14
HPSA-Specific Disk Attribute Files in /sys
/sys/class/scsi_disk/c:b:t:l/device/unique_id
This attribute contains a 32 hex-digit unique ID for each logical drive.
For example:
# cd /sys/class/scsi_disk/4:0:0:0/device
# cat unique_id
600508B1001044395355323037570F77
/sys/class/scsi_disk/c:b:t:l/device/raid_level
This attribute contains the RAID level of each logical drive.
For example:
# cd /sys/class/scsi_disk/4:0:0:0/device
# cat raid_level
RAID 0
/sys/class/scsi_disk/c:b:t:l/device/lunid
This attribute contains the 16 hex-digit (8 byte) LUN ID by which a logical drive or physical device can be addressed. c:b:t:l are
the controller, bus, target and lun of the device.
For example:
# cd /sys/class/scsi_disk/4:0:0:0/device
# cat lunid
0x0000004000000000
Supported ioctl() operations
For compatibility with applications written for the cciss(4) driver, many, but not all of the ioctls supported by the cciss(4) driver are
also supported by the hpsa driver. The data structures used by these ioctls are described in the Linux kernel source file
include/linux/cciss_ioctl.h.
CCISS_DEREGDISK, CCISS_REGNEWDISK, CCISS_REGNEWD
These three ioctls all do exactly the same thing, which is to cause the driver to rescan for new devices. This does exactly the
same thing as writing to the hpsa-specific host "rescan" attribute.
CCISS_GETPCIINFO
Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID).
CCISS_GETDRIVVER
Returns driver version in three bytes encoded as:
(major_version << 16) | (minor_version << 8) |
(subminor_version)
CCISS_PASSTHRU, CCISS_BIG_PASSTHRU
Allows "BMIC" and "CISS" commands to be passed through to the Smart Array. These are used extensively by the HP Array Configuration
Utility, SNMP storage agents, etc. See cciss_vol_status at <http://cciss.sf.net> for some examples.
