This is documentation we have tested and verified in our QA lab, and its known to be working on RHEL 5.5 with a P2000 G3 FC. Its based on the RH online storage guide. It assumes you're using multipathing.
List the disks by typing
multipath -l
This will give you the current host and lun numbers (x:0:0:n, where x is the host number, n is the lun number).
A sample output is below:
Once you've created the lun on the SAN, type (again, where x is the host number, n is the lun)
For each host number that should have access to the lun.
So looking back at our sample it'd be:
Next type
and you should now see the new device. At that point you should be able to add the volume to oracle ASM.

hi all :)
i'd like to remove a broken scsi tape device from a system p5 520. it is the only device on the external scsi hookup.
then i would like to add a new scsi tape device (same model).
is this, and if - how ?, doable without rebooting? (using aix 5.3)
best regards,

Hi,
Anyone can help me, just want to confirm, if possible adding a disk storage that we have a RAWDATA with +ASM in our database. If possible, what would you recommend "workaround used" from us to do and the preparation. And also how long the downtime will take.
Our disk continuous to grow,... (0 Replies)
Hi all,
I have an Oracle Enterprise Linux 5.5 server which is a virtual guest on a vSphere host.

hpsa
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
Since Linux 4.14, the following Smart Array boards are also supported:
Smart Array 5300
Smart Array 5312
Smart Array 532
Smart Array 5i
Smart Array 6400
Smart Array 6400 EM
Smart Array 641
Smart Array 642
Smart Array 6i
Smart Array E200
Smart Array E200i
Smart Array E200i
Smart Array E200i
Smart Array E200i
Smart Array E500
Smart Array P400
Smart Array P400i
Smart Array P600
Smart Array P700m
Smart Array P800
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 preconfigured 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, and so on. See cciss_vol_status at <http://cciss.sf.net> for some examples.
