If you add a new disk and a rescan in the GUI reports Failed without a comment, then go to the command line and do it manually (you will see whats happening an you will get a error-message)

server_devconfig ALL -list -scsi -disk

this shows the current
devices (not the new ones). Use this to compare against the later
“list” command

server_devconfig ALL -probe -scsi -disks

this interrogates the
backend for any new targets. You should check the output here to see
that the new devices are found.

server_devconfig ALL -create -scsi -disks

this creates the device
nodes on the datamovers and controlstation

server_devconfig ALL -list -scsi -disks

compare with the first run
to see the disk that has been added.

Now you can create your volumes, and filesystems with either the
nas_volume/nas_fs commands or the Celerra Manager.

Create new volume

First, create and assign new disks on IPstor and rescan your hpux-hardware paths (new style)

ioscan -N -fnk > io.lis

ioscan -N -fnC disk # unterschiedl. Disknr auf ClusterNodes möglich!

Remember all serial_numbers for later identification

scsimgr get_attr -D /dev/rdisk/disk??? -a serial_number

Create VG and leave space for a lun-extension (max DiskSize = 32MB*16384)

mkdir /dev/vgXXX
mknod /dev/vgXXX/group c 64 0x??0000 # must be unique in the cluster-env.
pvcreate /dev/rdisk/disk???
vgcreate -s 32 -p 64 -e 16384 vgXXX /dev/disk/disk???
vgextend vgXXX /dev/disk/disk???

manually define your PV-Groups

vi /etc/lvmpvg # there maybe differnet disk-devices on each host!

Create a FileSystem on an Logical Volume

lvcreate -s g -l 1 -m 1 vgXXX
lvextend -l <SIZE> /dev/vgXXX/lvol1
newfs -F vxfs /dev/vgXXX/rlvol1

# Import your VG an all other ClusterNodes and beware of different disk-devicefiles
# btw: if u  use your custom lvol-names or different-numbering-schemes use a mapfile
# “vgexport -p -v -m <mapfile> vgXXX > vgXXX.mapfile” copy and import.

vgimport vgXXX /dev/disk/disk?02 /dev/disk/disk?07 # use mapfile if necessary

Extend FileSystem / dynamic Disk

Expand your Lun on the IPStor

vgdisplay -v vgXXX # note your pv sizes
vgmodify -E -a vgXXX # do not use “-a -E”
vgdisplay -v vgXXX # PV size should be greater now

lvextend -l <SIZE> /dev/vgXXX/lvolYYY

fsadm -b $((PE_SIZE*LV_SIZE*1024)) /mountpoint

Usefull Commands

See multipaths per Lun

scsimgr lun_map -D /dev/rdisk/disk?23

Get WWI or serial_number for a disk

scsimgr get_attr -D /dev/rdisk/disk?04 -a wwid
scsimgr get_attr -D /dev/rdisk/disk?03 -a serial_number

echo “selclass type disk;info;wait;infolog” | cstm

Lun Multipath Overview (see dead paths)

ioscan -N -fnC lunpath

Remove VG / Disks

Get all Disk serial_numbers for a alter identification on IPStor

for i in `vgdisplay -v vgXXX|grep "PV Name"|awk '{print $3}'|cut -d "/" -f 4`;do
     scsimgr get_attr -D /dev/rdisk/${i} -a serial_number
done

Remove VG

lvremove /dev/vgXXX/lvolYYY # alle lvols löschen
vgreduce vgXXX # alle Disken bis auf eine wegnehmen
vgremove vgXXX

after installation SBG9.0.20 via OS_restore i had the problem that a ping to the default gateway only works for 5 sec.
we run two layer-3 subnets on one layer-2 net, so it could be a arp-broadcast problem.

(so it was time to get root-access to the sbg-instance -> see other article)

after playing around with kernel.arp values i found out that this settings would fix our problem

vi /etc/sysctl.conf
# Enable configuration of arp_ignore option
net.ipv4.conf.all.arp_ignore = 1

# When an arp request is received on eth0, only respond if that address is
# configured on eth0. In particular, do not respond if the address is
# configured on lo
net.ipv4.conf.eth0.arp_ignore = 1

=;) but this did not work,..it was set again to a value of “2″, … after some searches i found that someone had a similar problem an symantec patched these already und a file was made /data/os/etc/eth_arp_ignore.conf.readme

echo 1 > /data/os/etc/eth_arp_ignore.conf

Problem

When a system is connected to multiple SANs of the same type it is hard to tell what disk is on what SAN, or what disk is on what storage processor port it’s connected to.

Resolution

On Red Hat Enterprise Linux 5 all the data is stored in /sys and can be found independently of the Fibre Channel driver in use.

1) To find the Fibre Channel addresses of the HBAs on the machine, run the following:

# systool -c fc_host -v

(output trimmed for clarity)

  Class Device path = "/sys/class/fc_host/host8"
    port_name           = "0x10000000c9802436"
    node_name           = "0x20000000c9802436"

  Class Device path = "/sys/class/fc_host/host9"
    port_name           = "0x10000000c9802437"
    node_name           = "0x20000000c9802437"

On this particular machine, we have two HBAs acting currently as host8 and host9 (please notice that these numbers can change, they change every time the fibre channel driver is unloaded, reloaded, and can change across reboots). This host number is the H-value on HBTL SCSI addressing.

2) With the following command we can determine the fibre channel target WWN for the triplet HBT from HBTL SCSI addressing.

# systool -c fc_transport -v

(output trimmed for clarity)

Class = "fc_transport"

  Class Device path = "/sys/class/fc_transport/target8:0:0"
    node_name           = "0x50060160ba601693"
    port_name           = "0x500601683a601693"

  Class Device path = "/sys/class/fc_transport/target9:0:0"
    node_name           = "0x50060160ba601693"
    port_name           = "0x500601683a601693"

  Class Device path = "/sys/class/fc_transport/target8:0:1"
    node_name           = "0x50060160ba601693"
    port_name           = "0x500601603a601693"

  Class Device path = "/sys/class/fc_transport/target9:0:1"
    node_name           = "0x50060160ba601693"
    port_name           = "0x500601603a601693"

Where node_name, is the FC WWN of the Storage System, and port_name is the FC WWID of the Storage Processor Port.

3) With the following command, we can determine the mapping between SCSI HBTL addresses and the disks:

(sg_map is part of sg3_utils, and before running sg_map, it is necessary to have the sg module loaded on the system)

# sg_map -x

(output trimmed for clarity)

/dev/sg4  8 0 0 0  0  /dev/sdd
/dev/sg5  8 0 0 1  0  /dev/sde
/dev/sg6  8 0 0 2  0  /dev/sdf
/dev/sg7  8 0 1 0  0  /dev/sdg
/dev/sg8  8 0 1 1  0  /dev/sdh
/dev/sg9  8 0 1 2  0  /dev/sdi
/dev/sg10  9 0 0 0  0  /dev/sdj
/dev/sg11  9 0 0 1  0  /dev/sdk
/dev/sg12  9 0 0 2  0  /dev/sdl
/dev/sg13  9 0 1 0  0  /dev/sdm
/dev/sg14  9 0 1 1  0  /dev/sdn
/dev/sg15  9 0 1 2  0  /dev/sdo

4) From commands on (1), (2) and (3) we have the mapping from disk to HBTL SCSI addresses, and the mapping of SCSI address to fibre channel address. If, for instance, we want to see where the following multipath device is hosted, we do:

disc01 (3600601608e661a01486cd3c7f53ede11) dm-1 DGC,RAID 5
[size=10G][features=0][hwhandler=1 emc][rw]
\_ round-robin 0 [prio=2][active]
 \_ 8:0:1:0 sdg 8:96  [active][ready]
 \_ 9:0:1:0 sdm 8:192 [active][ready]
\_ round-robin 0 [prio=0][enabled]
 \_ 8:0:0:0 sdd 8:48  [active][ready]
 \_ 9:0:0:0 sdj 8:144 [active][ready]

5) We know already that it’s an EMC Clariion because the vendor is DGC, but I could have LUNs from more than one Clariion on this system, so let’s pick /dev/sdj as an example:

/dev/sg10  9 0 0 0  0  /dev/sdj

/dev/sdj = H:B:T:L = 9:0:0:0

Therefore for sdj we have, H=9 and HBT=9:0:0. From (1) and (2) we have:

Host HBA WWN:           0x20000000c9802437
Host HBA WWP:           0x10000000c9802437
Storage System WWN:     0x50060160ba601693
Storage Processor WWP:  0x500601683a601693

6) Doing for all disks:

               Local Port          Remote port          STORAGE
8:0:1:0 sdg    0x10000000c9802436  0x500601603a601693   0x50060160ba601693
9:0:1:0 sdm    0x10000000c9802437  0x500601603a601693   0x50060160ba601693
8:0:0:0 sdd    0x10000000c9802436  0x500601683a601693   0x50060160ba601693
9:0:0:0 sdj    0x10000000c9802437  0x500601683a601693   0x50060160ba601693

ATTENTION: look carefully at the ‘Remote port’ values, they normally differ only in a few bits.

In this particular case, we see that both sdd and sdj are on the same remote port, and sdg and sdm are on the same ports as well.

7) A storage system can have many ports. In most cases 2 or 4, but the Storage ID should remain the same. In sysfs we have 0x50060160ba601693, which maps perfectly to the storage WWN from the storage admin interface.

Current Storage System Name:      AX150
Storage System World Wide Name:      50:06:01:60:BA:60:16:93

Workaround, auf jedem Scanner durchführen:

da es unter umständen vorkommt, daß bei einer ändernung im SAN sich dier instance-numbers neu unter HPUX ordnen dann hilft nur eines,…neues manuelles verdahten der HardwarePathes (/etc/ioinit)

Liste der aktuellen HW-Pfade erstellen und korrigieren wo notwendig

ioscan -kfn | grep -e INTERFACE -e DEVICE | grep -v target | awk '{printf "%-40s %-20s %5s\n", $3, $1, $2}' > /stand/infile

ändern der Mappings von ext_bus instances (nur diese ändern!)

vi /stand/infile

Bsp.
8/0  ext_bus  0
8/4  ext_bus  3

==> Modify as :

8/0  ext_bus  3
8/4  ext_bus  0

Save ioconfig files :

mv /stand/ioconfig /stand/ioconfig.sav
mv /etc/ioconfig /etc/ioconfig.sav
shutdown -ry 0

5. From the console, stop boot process and boot in single mode :

Loading.: HP-UX Primary Boot: 0/2/1/0.0.0.0.0

war bei uns nicht notwendig da die ioconfig fehlte und hpux dadurch stehen blieb zum recovern.

6. The system starts witn an “ioinitrc” prompt.  Create ioconfig file :

cd /stand
/sbin/ioinit -c

7. update it with infile (This command will also reboot the system) :

/sbin/ioinit -f infile -r

ioconfig files will be cleaned.
