Section C: Migration from OMI solution to ADSM

Migration from OMI Enhadsmserv to IBM V3 ADSM

The following describes the necessary steps for migration from Enhadsmserv,
 OMI Enhanced ADSM Server for StorageTek Tape Drives and Tape Libraries ,
to
IBM V3 ADSM in support of StorageTek ACSLS library, Timberline drive,
Redwood drive and DLT7000 drive. Only perform those steps applicable to
your
configuration.

   1.Prior to installing V3 ADSM
     Stop all activities from Enhadsmserv.
   2.QUERY LIBRARY
     Obtain the Library Name of each library with:

     LIBTYPE=SSI

   3.QUERY DEVCLASS
     Obtain the DeviceClass Name of each device class with:

     DEVTYPE=STK
     lsdev -C -s scsi

     Obtain the current device special files and its SCSI associated
information from AIX. Note, all tape drives supported by the Enhadsmserv
device driver have
     the device special filename of "/dev/rmt(n)" with the device
description of "OMI AdvanTAPE - .......".
   4.QUERY DRIVE
     Record the SCSI configuration information and associate these device
special files with the Enhadsmserv DRIVE definition.
     Note: the drive name contains information about the ACS drive ID, i.e.
 STK_n_n_n_n. In addition, the first "n" is the ACS_id of the library.
   5.DELETE DRIVE libname drivename
     Delete all drives that were defined as DEVTYPE=STK or DEVTYPE=DLT that
 use OMI device driver from all libraries.
   6.Halt
     Halt the Enhadsmserv server, make a copy of your DB and DEVCONFIG
file.
   7.Use SMIT
     Use SMIT to delete these drive configurations from AIX.

     ps -ef  |  grep ssi

     Determine the SSI daemon process id.

     ps -ef  |  grep mini_el

     Determine the Event Logger daemon process id.

     kill  nnnn


     Kill the ssi and event logger daemons that were started by the
rc.adsmserv shell script.
   8.Install V3 ADSM and configure ADSM device drivers
     Install V3 ADSM server and device driver and use SMIT to re-configure
those deleted SCSI tape devices. All newly configured devices Note: the
     LIBTYPE and DEVTYPE for Enhadsmserv and V3 ADSM are different.

     LIBTYPE=SSI   --->  LIBTYPE=ACSLS
     DEVTYPE=STK  ---> DEVTYPE=ECART

   9.Upgrade to V3 data base
     rc.acs_ssi
     In the /usr/adsm.devices/bin directory, you should find rc.acs_ssi,
this is the shell script to invoke ACSLS SSI client daemon. Start the SSI
client daemon for
     the ACSLS support.

     ./dsmserv upgradedb

  10.Invoke the V3 ADSM
     Invoke the V3 ADSM and perform the data base upgrade
  11.QUERY LIBRARY libname
     After the server is initialised, the previous SSI library appears as
MANUAL library.
  12.UPDATE LIBRARY libname LIBTYPE=ACSLS ACSID=n
     Update all the previous SSI libraries to the new ACSLS libraries,
UPDATE LIBRARY to change LIBTYPE is only allowed for migration from SSI to
     ACSLS.
  13.AUDIT LIBRARY libname
     Audit the library to reinitialise the ACSLS library structure. All
ADSM checked-in volumes in the libraries will be locked during the AUDIT
process. Depends
     on the size of the library it may take a while before the library is
ready for operation.
  14.QUERY LIBV libname
     Verify all library volumes and their status.
  15.DEFINE DRIVE libname drivename DEVICE=/dev/mtn ACSDRVID=n,n,n,n
ONLINE=YES
     Re-define the drives to the library. Note, the ACSDRVID n,n,n,n values
 are obtained from the drive name of STK_n_n_n_n and the device
  16.QUERY DEVCLASS classname
     The DEVTYPE=STK of the previous DEVCLASS appeared as OMI_STK which is
an invalid type for V3 ADSM.
  17.UPDATE DEVCLASS classname DEVTYPE=ECART
     Update all OMI_STK DEVCLASSes with the new DEVTYPE, UPDATE DEVCLASS to
 change DEVTYPE is only allowed for migration from
     OMI_STK typ

Subject:  Converting from V2 w/Enhanced Server to V3





Can anybody tell me where to find any documentation/hints/suggestions on
converting from ADSM/AIX V2 with ADSM Enhanced Server (STK 9710 support) to
ADSM/AIX V3 with native ACSLS support?

I thought I had seen something at one time in a README file, but I can't
find it now.

Thanks.....
