XSTM readout and EMC Array

The readout from xstm shows the following.

PCU Buc adapter
Fibre Channel Interface
Fibre Channel Driver
EMC Array (6)

This would indicate a disk array of 6 disks to form a LUN????

Re: XSTM readout and EMC Array

I seriously doubt it, but one way to find out is to run emc's inq utility or one of their other "graphical" utilities.

Re: XSTM readout and EMC Array

To figure out the LUN details of EMC:

use #syminq
or #inq

This will list the luns seen by the system including their sizes.

The luns are not physical disks , but splits from the physcial disk. The split is done at the EMC level through a bin file. You can look it up using EMC console utility "symmconsole".

The EMC engineer should be able to give you
a hard copy of the binfile layout.

all the emc binaries should be under /opt/emc.
do a find /opt/emc -type d -name bin
and look into bin directories.

Take it easy.

Re: XSTM readout and EMC Array

This is the number of FA seen by all your HBA. So if your Symm as 6 FA connected into a switch or a hub and you have 2 HBA you will see 6 device (is the Volume Logix database, read only hyper) needed by the volume logix client.
