Creating node /sapmnt/$(SAPSYSTEMNAME) with type DIRECTORY failed

[Former Member]

Hello,

I´m doing a SAP Gateway installation in a Solaris SPARC 64bit (I´m using the Software provisioning manager 1.0 SP03). I running the SWPM with root user.

During the installation the SWPM stops with an error in the phase 2 - Install common system files

I checked the sapinst.log file:

I tried to overcome this issue and so I tried to give full permissions to /sapmnt directory... but even with root user it doesn´t allowed me, the output is the following (currently the /sapmnt directory has 755 permissions):

liszgpora001# who am i

Can you help me please to solve this problem?

Thank you,

If the folder permissions are correct, you need to look at the NFS permissions on the exporting host and the mount options on the importing host.  I have never done this on Solaris, but take alook at this:  http://www.dswkim.org/tips/tu228.html

FSL-02036  Unable to create node /sapmnt/GAT with type directory: Read-only file system.

That message is pretty understandable

Check how the file system is mounted. - mount

Are you able to create the directory manually ? - mkdir /sapmnt/GAT

Hello Reagan,

I´m not able to create the directory manually in DB host:

liszgpora001:azpadm 3% mkdir GAT

mkdir: Failed to make directory "GAT"; Read-only file system

But in CI host this is possible!

samid

mkdir: Failed to make directory "GAT"; Read-only file system

This is a problem with the way the NFS was exported from the source host.

You need to make sure that the filesystem has permissions rw (rather than ro) on the /etc/dfs/dfstab on the source host.

That should solve your problem

Hello Juan,

I checked the /etc/dbs/dbstab in CI host (source host):

liszgpsap003# cat /etc/dfs/dfstab

#       Place share(1M) commands here for automatic execution
#       on entering init state 3.
#
#       Issue the command 'svcadm enable network/nfs/server' to
#       run the NFS daemon processes and the share commands, after adding
#       the very first entry to this file.
#
#       share [-F fstype] [ -o options] [-d "<text>"] <pathname> [resource]
#       .e.g,
#       share  -F nfs  -o rw=engineering  -d "home dirs"  /export/home2
share -F nfs -o root=liszgpsap004:liszgpora001:liszgpsap001:liszgpsap002:liszgpsap003,anon=0 -d "SAP trans" /usr/sap/trans
share -F nfs -o root=liszgpsap004:liszgpora001,anon=0 -d "SAP exe" /sapmnt/AZP/exe
share -F nfs -o root=liszgpsap004:liszgpora001,anon=0 -d "SAP global" /sapmnt/AZP/global
share -F nfs -o root=liszgpsap004:liszgpora001,anon=0 -d "SAP profiles" /sapmnt/AZP/profile
share -F nfs -o rw,anon=0 /usr/sap

What I have to edit here?

Ok, because you are installing the Gateway instance the install is local, can you check your mounts on the local DB host...

Regards, Juan

[Former Member]

From your output from mount command:

/sapmnt on liszgpsap003:/sapmnt remote/read/write/setuid/devices/rstchown/xattr/dev=5d40001 on Thu Oct 17 22:11:25 2013

This does not correlate with dfstab content.

liszgpsap003:/sapmnt

Your /sapmnt is and nfs mount coming from liszgpsap003 that is why you cannot create the Gateway SID under it.

from your previous post

share -F nfs -o root=liszgpsap004:liszgpora001:liszgpsap001:liszgpsap002:liszgpsap003,anon=0 -d "SAP trans" /usr/sap/trans
share -F nfs -o root=liszgpsap004:liszgpora001,anon=0 -d "SAP exe" /sapmnt/AZP/exe
share -F nfs -o root=liszgpsap004:liszgpora001,anon=0 -d "SAP global" /sapmnt/AZP/global
share -F nfs -o root=liszgpsap004:liszgpora001,anon=0 -d "SAP profiles" /sapmnt/AZP/profile
share -F nfs -o rw,anon=0 /usr/sap

basically you should have /sapmnt/AZP mounted on your distributed hosts not /sapmnt

I would unmount /sapmnt from liszgpsap001 and mount /sapmnt/AZP from liszgpsap003 , then you should be able to create local new entries under /sapmnt in liszgpsap001

Hello Juan,

Ok... but tell me one thing, it is mandatory to perform a SAP Gateway installation in a /sapmnt directory?! Can I install it locally, on DB host? ...the main reason for this installation it´s because I need to install a SAP gateway on DB host to connect the CI and DI instances/hosts with DB host through the RFC SAPXPG_DBDEST_LISZGPORA001 (for the DB13 activities (notes 1914589, 446172)).

I posted this situation some days ago in the following url:

http://scn.sap.com/thread/3437170

During the installation of SAP Gateway the SWPM asked me the following value:

Can I install it locally, on DB host?

Once you correct the mount to /sapmnt/AZP your /sapmnt directory is local. So the gateway will be a local install on the DB host.

[Former Member]

Hello Ruan,

Ok... but there are an alternative to that solution?... a workaround? For instance, if I created manually the /sapmnt/GAT directory in source host, it doesn´t correct this error?

Thank you,

samid

[JPReyes]

There is no point to install a local gateway on a mounted NFS.

Once you have done the changes above you can resume your install without issues, the /sapmnt/GAT will be local.

Remount file system with rw option.

Hi,

As suggested please change the permission for /sapmnt and proceed, this will work.

Hi Samid

Kindly go thru the SAP Note 1432833

Thanks

[AtulKumarJain]

Hi Samid,

Please change the permission for /sapmnt as suggest by deepak.because your FS is only read only mode .

It will work after that.

Hi Samid,

I guess you have distributed environment and you are installing SAP gateway on the DB host where you have /sapmnt mounted from CI host.

FSL-00009  System call failed. Error 30 (Read-only file system) in execution of system call 'mkdir' with parameter (/sapmnt/GAT, S_IRWXU | S_IRWXG | S_IRWXO), line (471) in file (syuxcpath.cpp), 

Please change the permission of /sapmnt on the source server from where it has been exported.

make it 777 . Post this it should work.

Hope this helps.

Hello Deepak,

Thanks, in fact this is a distributed SAP system and I´m doing this on the DB host. So, I went to CI host and I change the permissions of /sapmnt to 777 with success:

liszgpsap003# chmod 777 sapmnt

liszgpsap003# ls -ltr

drwxrwxrwx   3 root     sapsys         3 Sep  5  2012 sapmnt

I retry the installation of SAP Gateway but unfortunatelly it show me the same error:

[Former Member]

Hello Atul,

There is no /sapmnt/GAT... that is the error here! The installation process can´t create the GAT directory... I believe this must be related with some export permissions of directory /sapmnt between the hosts.

Yes Samid,

Could you please check same with os admin they will help you in this case.
