VxVM not detecting newly add LUN

Is this is a clustered setup ?

Have you tried moving the disk.info file ?

Gaurav

Hi Gaurav,

Yes this is a Service Guard cluster.

I haven't moved "disk.info" file as of yet. I just wanted to confirm if I delete /etc/vx/disk.info file and recreate it using - vxdctl init `hostname` command will it affect the system ?

Thanks

hi timus,

vxdctl init `hostname`  initializes the volboot file & not disk.info ..  we need not to do this...

before suggesting next actions, can you confirm following:

# /etc/vx/diag.d/vxdmpinq /dev/rdsk/c19t5d6

(path to vxdmpinq may be different, search for it if not in /etc/vx/diag.d)

Here would be my suggestion once you confirm me above:

to re-init the disk.info file we need to restart vxconfigd daemon.. but since you are using the cluster, you need to make sure that your services/applications are taken care properly..

what I would suggest is:

-- make sure your applications are frozen or offline or moved to other node

-- mv /etc/vx/disk.info /etc/vx/disk.info.old

-- rm /dev/vx/rdmp/*

-- rm /dev/vx/dmp/*

-- scan all devices from HP using ioscan -fnC

-- vxconfigd -k -x syslog  (restart vxconfigd daemon)

This will re-generate all your device tree in /dev/vx/rdmp & /dev/vx/dmp .. also it will re-create the disk.info file

Gautam,

Below is the o/p of vxdmpinq -

/etc/vx/diag.d/vxdmpinq /dev/rdsk/c19t5d6

Inquiry for /dev/rdsk/c19t5d6, evpd 0x0, page code 0x0
Vendor id             : DGC
Product id             : CX3-80WDR5
Revision Number        : HP03
Serial Number          : Ch2 CONTROLL

Thanks,

Sumit

Hi Sumit,

Might be a silly questions but does the ioscan -fnC show the new disks with /dev/rdsk/ entries? I had something similar last week where they  were listed by ioscan, but did not have device entries e.g. /dev/rdsk/c10t0d0

if so, run insf -e

then

vxdisk scandisks

then 

vxdctl enable

Hi Riaan,

Yes the new device (LUN) has proper device file entries in /dev/dsk and /dev/rdsk . It is properly detected by OS. I am able to read/write to the new device using "dd".

Thanks,

Hi Gaurav,

Performed the following steps in the below mentioned order, but the problem still persists, any suggestions why is it happening ?

   mv /etc/vx/array.info /etc/vx/array.info.old
   mv /etc/vx/disk.info /etc/vx/disk.info.old
   rm /dev/vx/dmp/*
   rm /dev/vx/rdmp/*
   vxddladm disablescsi3
   ioscan  -fnC disk and insf -e

   vxconfigd -k -x syslog

Thanks

Is anything excluded ?

# ls -l /etc/vx/*exclude*

If any exclude file is there, can you paste the contents of the file ?

Also paste

# vxdmpadm listexclude all

# vxddladm listexclude all

# vxdmpadm listenclosure all

# vxdmpadm listctlr all

Can you also tell the exact model of the array ?

Gaurav

Did you label the disk ? If you are using EMC powerpath, then you should also run "powermt config" before identifying the disk in veritas.
