How to convert agile DSF to legacy DSF and vice versa in HPUX 11.31

[sksarangi]

Hi,
I have few agile DSFs and few legacy DSFs on my server. Some agile DSFs and mapped to legacy DSFs, as follows(ioscan -m dsf). There are some additional agile DSFs which are not mapped to legacy DSFs. I would like to change these DSFs to their corresponding legacy names. Also how to reverse the action.
you can see disk3 and disk14-21 are mapped to corresponding legacy DSFs. But disk22-37 have no corresponding legacy dsf.

Hi,

The best way is to download and read the manual.

www.docs.hp.com/en/MassStorageStack/The_Next_Generation_Mass_Storage_Stack.pdf

I read the doc "The_Next_Generation_Mass_Storage_Stack.pdf ". But could not get the above task by either 'mksf' or insf' cli.
If someone can explain, it would be helpful.

hi

What does these commands say , please post the O/P
#ioscan -kfnCdisk
and
#ioscan -kfnNCdisk
#ioscan -m hwpath
What is the HP-UX Release Version, please say that will help know the system better.
What and all are the QPK and HWenable releases.(swlist )
regards

Hi here is the details from the cmdline outputs attached in the doc "hp-dsf-screenshot.txt"
Thanks,

What exactly do you mean here? Change the physical devices that you use in your LVM? (or VxVM?)

[sksarangi]

it is something like creating a legacy DSF for an existing agile DSF and vice versa. The physical device remain the same.
For Ex:
spea119 #ioscan -m dsf /dev/rdisk/disk21
Persistent DSF Legacy DSF(s)
========================================
/dev/rdisk/disk21 /dev/rdsk/c1t7d7
spea119 #ioscan -m dsf /dev/rdisk/disk22
spea119 #
I would like to create an equivalent legacy DSF for /dev/rdisk/disk21
Probably 'mksf' cmd may help, not sure how to do.

[Simon Hargrave]

Have you tried "insf -e" to force install of all device special files? Then possible "insf -L" too?

[Eric SAUBIGNAC]

Bonjour,

I am a bit surprised by the value 255 found in legacy hardware path like 0/4/1/0.1.0.255.0.7.1 and I wonder if you have correctly configured your EMC Storage.

See those thread that are speaking of SPC-2 flag at EMC side :

I had the same issue, and the issue needs to be addressed by EMC Vendor.

The attached doc was followed !!

Also please assign points to your thread if you find your answers

No point for this please

Try #ioscan -L

[sksarangi]

I tried setting the SPC2 bit for the device. But that did not help either.
"symmask -sid 072 set hba_flags on SPC2 -enable -wwn 5001438001321214 -dir 15C -p 1"
I am sure there is something wrong with symm configuration. if you notice the cmd output of "ioscan -m hwpath" ( attached file before), we can see "Legacy H/W Path" for few devices and also it contains something like "0/4/1/0.1.0.255.0.7.1", the no "255" looks incorrect.
Please advice any solution.
Thanks,

[Duncan Edmonstone]

so EMC usually have a host connectivity guide per OS. Have you got a copy of this - no doubt it lists all the requirements for running 11iv3?

Why not just ask EMC to check your configuration? They're usually pretrty good at this sort of request.
