Hello everyone.
I found a lot of very useful information here but this time I have some
doubts so I decided to subscribe and ask.
Recently we upgraded our hardware (z9 + DS6000 - z114 + DS6000 + XIV) and
we have to make some choices.
There is a chance that at some point we will have to get rid of

Googling around looks like SLES doesn't support it - the utilities are no
longer included ... but I believe all you'd need is the jfsutils rpm.
Anyway - yes - quite possible. I searched on 'jfs s390x' to find info..

I know that in general ECKD win over FCP.
I'd be not so sure about that. You need at least a bunch of aliases on the
ECKD side to get into the same ballpark of speed. (With FCP AIUI Linux

Hi there,
Is it possible to mount an AIX filesystem(JFS) on zLinux?
One of my customer is considering about zLinux as their batch system.
Their existing AIX systems are using Oracle, the customer wants to
replicate their AIX Oracle
Thank you for all of your comments.

First of all, I have to check that the customer is using LVM or not on AIX.

pretty easy to manage, multipathing is working fine - no doubts over here.

I applaud you for your decision to place the user DB data on FCP SCSI. Out
performs ECKD and allows you to have ALL LUN after formatting and inherent
multi pathing NOT the 70% or so. the best part is that you now have made
zlinux less mainframe and more main stream. Other platforms can now
I had this issue also with SLES10(SP3, I suspect SP4 would work fine), SLES9,
and RHEL 5.6. A `make install` from the source will get you around this, but
that might not be an option for all people. Otherwise you have to install a
different version of RPM, however when I googled, it didn't

Thank you all for your help (I was asking about EDEV vs FBA)
Reading all your emails, I've decided to give a try with EDEV.
I am already having a big problem or perhaps just lack of a knowledge.
I decided to (for now) use EDEVICE attached to linux guest (without
minidisks).

Maybe have the box ticked to format the device first? You shouldn't.
You can partition it with fdisk but I have not found the magic spell

But the approach would be to create mini disks and scatter
Hi Grzegorz - hello - been a while! I can tell you that I have clients
that use EDEV FBA for non-production databases, mostly but not
exclusively Oracle. We're using minidisks with underlying multipathed
EDEVs.
Good ole' DIRMAINT is in charge of the storage management.
It works well.

Just by way of further clarification of my Mark's accurate comment:
1. VDISK is in one of theses states: in core memory, paged out, or never
referenced, i.e. it's treated as memory albeit looking like FBA. No
actual FBA I/O occurs.
2. EDEV exists at least in the hardware. Feels like FBA to the
