Issue in TREX 7.1_62 installation on Linux

[Former Member]

Hello,

I am trying to install TREX 7.1_62 on Linux server.

I put /sapmnt as my installation location in sapinst.

While installing TREX instance the installer is terminating with below log:

_install.log

Traceback (most recent call last):

  File "/sapsw/TREX_71_62/tx_trex_content/TX_LINUX_X86_64/support/setuplib.py", line 5013, in createLinked

I tried to use other locations like /usr/sap/D82 as installation location, inthat case it tries to create link like

/usr/sap/D82/D82 --> /usr/sap/D82

My server has /sapnt/D82 and /usr/sap/D82 as separate mount points.

/dev/mapper/vg_dd82-lvusapd82_3

                       47G  1.1G   46G   3% /usr/sap/D82

/dev/mapper/vg_dd82-lvusapd82_4

                      4.7G  139M  4.6G   3% /usr/sap/SMD/SMDA90

itsusravmdd05.jnj.com:/vol/itsusravmdd05_btb/btb_fsrf_sapmnt_d82

                       25G     0   25G   0% /sapmnt/D82

I dont understand why installer is trying to create a softlink between

/sapmnt/D82 and /usr/sap/D82

Please share any information you guys are having.

Thanks & Regards,

I faced the same problem as well. The reply of Maurizio is the correct "workaround" here.

Same problem here with same mount points.

Solved with following commands:

umount /usr/sap/SID

cd /usr/sap

rm -r SID

SAP installation try to create symbolic link from /usr/sap/SID to /sapmnt/SID

SID under /usr/sap should not exist.

Hey Tejas,

1. Firstly cleanup your failed installs.

2. Use /usr/sap as your installation directory.

By default (when I use command line) TREX installs into /usr/sap with the SID and SYSNR you provide.

Hi Amerjit,

Thanks for your reply.

I tried to install under /usr/sap and its successfull.

I performed all the tests and they are successful.

However mount point /sapmnt/D82 is blank and has no data.

This is not a standard behaviour.

I have earlier installed version 57 without any issue.

Any idea if there is any change in TREX 7.1 version D62?

I tried to browse through notes/blogs/forums but did not get any useful information.

Thanks & Regards,

Hey Tejas,

I can't recall from which version/patch that the software stopped being installed into /sapmnt.

All my TREX installations in the last couple of years (manual not sapinst) have all gone into /usr/sap

Anyway, I'm glad you got it installed.

Close out the post as answered and enjoy.

Cheers,

A.

Hi Amerjit,

TREX got installed but /sapmnt/D82 has no data in it.

Is this fine?

When I installed version 57, the directory structure was perfect and /sapmnt/SID has all the global directories i.e. exe, global, profile

So I was expecting same behaviour for version 62 as well.

Thanks & Regards,

Hey Tejas,

All my installations (>= 7.10.57.00) are running fine in /usr/sap/>SID> for years now.

http://help.sap.com/saphelp_nwes72/helpdata/en/45/6ddd60fe7b40bfe10000000a1553f7/content.htm

I seem to recall on TREX 7.0 that it installed into /sapmnt and /usr/sap/<SID>

Cheers,

Amerjit

Hi Tejas

1. You can use the installation media on Trex 7.10 SP57 after that you can before the "Update a Trex system" to SP62.

2. Kindly follow the Trex installation and configuration steps from the SCN link

Could you share the full error message as snapshot?
