246.0. "PASTIT - Disk Replacement Programme" by SHAPES::SYSTEM () Tue Jun 06 1989 11:34

Dear All,

PASTIT will be unavailable from Friday June 16th at 17:30 until Monday 
19th June 1989 for PASTIT's disk replacement programme (See note 
190.14 in SYSTEM_MANAGEMENT notes file).

All RA81 & RA82 data disks will be replaced by RA90's.  You will see 
an improvement in disk space.

The table below shows the current physical disks and the disks that 
the workload will be backed up to.

There will be a number of things that will have changed after the 
workload moves:

1.  The physical device names will have changed (See table below).

2.  The Disk Label's will have changed (See table below).

3.  Logicals names for the disks have changed (See table below).

Current Disks      Future Disk    Disk Label     Logical Name	  Device Type

$21$DUA0:	   $21$DUA80:	  VAXVMSRL2	 SYS$SYSDEVICE:	  RA82

$21$DUA1:	   $21$DUA81:	  DATA1		 DISK$DATA1:	  RA90
$21$DUA10:

$21$DUA2:	   $21$DUA82:	  DATA2		 DISK$DATA2:	  RA90

$21$DUA4:	   $21$DUA83:	  DATA3		 DISK$DATA3:	  RA90
$21$DUA12:

$21$DUA5:	   $21$DUA84:	  DATA4		 DISK$DATA4:	  RA90

There are a number of changes to be made after the move some of which 
you will have to carry out:

1.   Please ensure that you have not hard-coded physical device names 
     in your command procedures or programs.

2.   Re-submitt personal batch jobs.

3.   We will leave current logicals pointing to the relevant disks 
     until Friday 23rd June.  Please ensure that you have modified 
     your procedures or programs to reflect the new logicals eg: 
     DISK$DATA1:, DISK$DATA2: etc. by that date.

Below is a table showing the current logicals and their future 
equivalents.  All logicals in the first column will be removed on 
Friday 23rd June.
