Symptom
There is not enough memory capacity available on mount point
/hana/exeini of a Dell HANA scale-up appliance to install an update or
an additional SAP HANA instance.
Other Terms
SAP HANA, exeini, low memory capacity, full scale-up, Dell
Reason and Prerequisites
The /hana/exeini mount point is too small for SAP HANA scale-up
systems that were not initially delivered with SAP HANA SPS06. Due to
the increasing size of the SAP HANA update packages, as well as the
possible installation of additional SAP HANA instances, we recommend
moving all data from the mount point /hana/exeini to the
/hana/data/exeini folder.
To perform this change, you have to stop all the SAP HANA databases on the SAP HANA scale-up system. Therefore, schedule a time window of approximately one hour to transfer the data. The database will be unavailable during this time. You will need access for the root user for these changes.
We recommend backing up the SAP HANA database and its configuration before making the changes.

Solution
To perform this change, you have to stop all the SAP HANA databases on the corresponding SAP HANA scale-up system.
In this example, we assume an SAP HANA system that has only one SAP HANA instance, with the system ID (SID) BST. If you have additional HANA instances, repeat steps 2 and 3 for each instance.
1) Log on to the HANA scale-up system with the root user
2) Enter the command su - <sid>adm, replacing <sid> with the system ID (BST in this example) in lower-case. In this example: su - bstadm
3) Enter the command HDB stop to stop the running database and then enter the command exit to return to the previous context
4) Enter the command /etc/init.d/sapinit stop to stop the SAP host agent
5) Enter the command mkdir /hana/data/exeini to create a subdirectory called exeini under /hana/data
6) Enter the command cp -avr /hana/exeini/* /hana/data/exeini to copy all data from /hana/exeini to /hana/data/exeini
7) In the /etc/fstab file, change the line that starts with /dev/vg0/exeini to a comment, so it looks like this:
#/dev/vg0/exeini /hana/exeini ext3 noatime,data=writeback,barrier=0 1 2
8) Enter the command umount /hana/exeini to unmount the mount point /hana/exeini
9) Enter the command rmdir /hana/exeini to remove the /hana/exeini directory
10) Enter the command ln -s /hana/data/exeini /hana/exeini to create a symbolic link from /hana/data/exeini to /hana/data
11) Enter the command su - <sid>adm, replacing <sid> with the system ID (BST in this example) in lower-case. In this example: su - bstadm
12) Enter the command HDB start to start database and then enter the command exit to return to the previous context
