error when create volumn group : no device files for the selected device were found in /dev

[Kuang Chen]

we just finished configuration EVA3000 to connect our server. isocan see disk ok.

disk 3 255/255/0/0.0 sdisk CLAIMED DEVICE HSV100 HP
/dev/dsk/c11t0d0 /dev/rdsk/c11t0d0

But we I used sam to create volumn group, I had the error:
no device files for the selected device were found in /dev

Is any setup EVA3000 before?

Thanks
KC

Do you have the proper device file installed on /dev directory? This command will recreate the missing device files:

# insf -e

[Jeff Schussele]

Hi KC,

Think that device you're seeing is analogous to an EMC "gatekeeper" disk & is not an actual LUN.
Have you run

ioscan -fnC disk

and an

insf

since the storage was carved & zoned?

Rgds,
Jeff

[Kuang Chen]

I used ioscan -fnC disk found out disk ok
disk 3 255/255/0/0.0 sdisk CLAIMED DEVICE HSV100 HP /dev/dsk/c11t0d0 /dev/rdsk/c11t0d0

I also ran insf -e
I saw that
insf: Installing special files for sdisk instance 3 address 255/255/0/0.0

still can not use sam create volumn group

any ideal

hi,

what does "diskinfo /dev/dsk/c11t0d0" return? disksize 0?

regards,
Thierry.

[Kuang Chen]

Yes, diskinfo return right size of disk:
SCSI describe of /dev/rdsk/c11t0d0:
vendor: HP
product id: HSV100
type: direct access
size: 104857600 Kbytes
bytes per sector: 512

I have a sneaky suspciion the problem is due to SAM not currently recognising and supporting the EVA arrays. Have you tried doing pvcreate on hte luns by comand line?

[Kuang Chen]

No, I only used sam.
I am not sure the my command is right, can you check for me?

#pvcreate /dev/rdsk/c11t0d0
#mkdir /dev/vg05

I am not sure about mknod and vgcreate command. Can you help me out?

Thanks
KC

[Steven E. Protter]

pvcreate -f /dev/rdsk/c11t0d0
mkdir /dev/vg05
/dev/newvg/group c64 0x050000

You may need to adjust the last figure for your volume group name.

vgcreate ...

One thing to check is the device files for your alternative paths. Do you have alternate PVlinks available for these disks? If yes, does that show on the ioscan output. Some times, SAM will identify these alternate paths and will error out if the device file are not present.

Also fdr command line:

# pvcreate /dev/rdsk/cxtydz
# mkdir /dev/vgXX
# mknod /dev/vgXX/group c 64 0x0?0000 ( the last number is the minor number. e.g: for /dev/vg01 volume group, the minor number is normally 0x010000)
# vgcreate /dev/vgXX /dev/dsk/cxtydz (you can also replace vgcreate with vgextend if you want to extend an existing VG)

Steve, Shiju thanks for help me out menually create volumn group for EVA.

Melvyn,

Yes there is a SAM cumulative patch for HP-UX version 11.11 - PHCO_28123. This what the patch description says:

"SAM does not recognize the following new

Dual port PCI-X 2 Gb/1Gb Fibre Channel Host
Bus Adapter (Product# A6826A)
EVA GL - HSV110
EVA GL Lite - HSV100
SA5304/256 4 Port RAID HBA - (Product #: A7143A)

I have checked and the patch PHCO_28123 is already installed but the problem still persists.
Can anyone tell how to get SAM recognize our EVA3000 HSV100
