Steven E. Protter — Thu, 22 Sep 2005 07:57:37 GMT

insf -C disk

Will create new ones for disk newly transferred to a system.

There are also procedures for renumbering hardware instances.

After masking the LUNs to a host, iosan -fnC disk, then insf -e -C disk

Re: How do you create /dev's for EMC BCV's?

Stuart Abramson — Thu, 22 Sep 2005 09:13:05 GMT

1. You must "present" the BCV volumes to the host in ECC:
o Zone the HBAs to the FAs.
o Present the HVs to the FA.
o LUN Mask the HVs to the HBA.
- Activate VCMDB

2. Then the BCV must be in "split" state from the STD to discover on host. Can't be synched. Not visible when synched.

3. Disocver on host:
o symcfg discover
o ioscan
o insf -e
o symcfg discover

4. Add ot PowerPath:
o powermt restore
o powermt check
o powermt config
o powermt save

Mitchell Johnston — Thu, 22 Sep 2005 11:34:05 GMT

This did not work. I did not get any errors, it just did not create the device files. Could it be an issue with masking?

Re: How do you create /dev's for EMC BCV's?

Stuart Abramson — Thu, 22 Sep 2005 12:19:09 GMT

It could be zoning, presentation, masking, physical connection or any other problem.

What does "symdev list" show for this Symm?

Try:

symdev list -sid SYMMID -bcv

symdev show HVNUMBER

symmaskdb list -dev HVNUMBER

Re: How do you create /dev's for EMC BCV's?

Geoff Wild — Thu, 22 Sep 2005 12:30:50 GMT

If it didn't work - then the disks can not be "seen" by the host....you have to check EMC and/or zoning.

Just run /usr/symcli/bin/syminq on host - to see if the disks are there...

Re: How do you create /dev's for EMC BCV's?

Matthew Ghofrani — Fri, 23 Sep 2005 10:29:33 GMT

If you still don't see the disks and assuming they are zoned correctly to the WWN, try discovery like:
symcfg discover
ioscan -fnC disk
insf -e

Stuart Abramson — Fri, 23 Sep 2005 12:57:14 GMT

correct me if I'm wrong, but it looks like you have what you want:

BCV dev 048 (HyperVolume Serial Number) has device file /dev/rdsk/c16t1d7
dev 04C has device file /dev/rdsk/c16t2d0

etc

So, what's the problem?

Re: How do you create /dev's for EMC BCV's?

Stuart Abramson — Fri, 23 Sep 2005 13:00:26 GMT

Okay, theh problem is that the following two volumes aren't visible on your server:

0060
0064

Well, check the presentaton (mapping) and LUN-masking on these two HVs. Then do the discovery sequence again.

Re: How do you create /dev's for EMC BCV's?

Stuart Abramson — Mon, 26 Sep 2005 12:48:39 GMT

Mitch:

Here is what it looks like to me:

Your server has two HBAs connected to the SAN (or direct - I forgot to check - but probably SAN):

0/1/0/0 /dev/td5 ..04d8
0/1/1/0 /dev/td5 ..069a

Most of the BCVs are presented to FA 01B:0. They may have another path, I didn't see it (I might have missed it.)

The presented ones are: 48, 4C, 50, 54, 58, 5C, 6C, 7D.

The following are NOT presented to 01B:0 :
60, 64, 68, 71, 75, 79.

CHECK THE PRESENTATION ON THESE GUYS!

You SHOULD present them dual-access to 2 FAs and then zone the FAs to two different HBAs.

All of the BCV volumes are LUN-masked to HBA ..cb76, which isn't a player in this config, so not important.

The LUN-mask string to ..04d8 is missing the missing HVs. CHECK THE LUN MASKING FROM 60, etc, to WWN/HBA ..04d8.

No volume at all is LUN-masked to HBA ..069a, which is part of this server and connected to the SAN.

I got this from your output above and from the grab. EMC will figure this out also..

None of your HyperVolumes are LUN-masked to ..069a. You should do

BCV's are standard disk devices.

inq -et | grep < device id like 0048 >

will give you the way the device is presented to the host

for eg

inq -et -nodots | grep 07E8
/dev/rdsk/c15t0d6 :207E8000 :REG :N/A :FBA :FIBRE :S :SYMM6 :RAID-S : :R10A-1 :20050330

/dev/rdsk/c32t0d6 :207E8000 :REG :N/A :FBA :FIBRE :S :SYMM6 :RAID-S : :R07A-1 :20050330
/dev/rdsk/c36t0d6 :207E8000 :REG :N/A :FBA :FIBRE :S :SYMM6 :RAID-S : :R07B-1 :20050330
/dev/vx/rdmp/c15t0d6 :207E8000 :REG :N/A :FBA :FIBRE :S :SYMM6 :RAID-S : :R10B-1 :20050330
with the FA displayed in the end .

If the bcv is not presented then check for

1. Masking to the HBA , FA Port
2. Mapping to the FA port .
#. Zoning of the HBA to the FA port ( which I assume should be correct ).
