The Ultra Enterprise 3500 server (E3500) is a special case when replacing
internal disks that are under Sun Enterprise Volume Manager[TM] (SEVM) 2.x, or
Veritas Volume Manager (VxVM) 3.x control.  The E3500 has dual ported FC-AL
drives, making it similar to the A5x00 array.  This procedure should be used for
the following:

 	Replacing a simple datadisk
 	Replacing a mirrored disk under Volume Manager control

The procedures are all individually explained in various documents for A5x00,
and Volume Manager related documents. The purpose of this document is to bring 
these procedures together in one document for FC-AL disks in the E3500 enclosure.
                           

REPLACING A SIMPLE DATA DISK
1. Ensure the following patches are installed:
	Solaris 8 
	Luxadm patch - 109529-06 or higher

	Solaris 7 
	IB & Luxadm patch - 107473-07 or higher

	Solaris 2.6	
        sf/socal/ib/luxadm patch - 105375-10 or higher
 	ssd patch - 105356-08 or higher

	Solaris 2.5.1
 	sf/socal/ib/luxadm patch - 105310-08 or higher
 	ssd patch - 104708-16 or higher

    These provide support for the luxadm commands on the E3500.

2. Unmount the disk and then stop it with the command

	luxadm stop <logical path or physical path or WWN ...>

3. Remove the device entries, the following command will complete this

	luxadm remove_device <logical path or physical path or WWN ...>

4. Replace the disk, then

	luxadm insert  <no arguments required>                        

   This will recreate the device entries, the device is now ready to be used.

 
REPLACING A MIRRORED DISK UNDER VOLUME MANAGER CONTROL

1. Ensure the the following patches are installed:
	Solaris 8 
	Luxadm patch - 109529-06 or higher                        

	Solaris 7 
	IB & Luxadm patch - 107473-07 or higher
	
	Solaris 2.6	
        sf/socal/ib/luxadm patch - 105375-10 or higher
 	ssd patch - 105356-08 or higher

	Solaris 2.5.1
 	sf/socal/ib/luxadm patch - 105310-08 or higher
 	ssd patch - 104708-16 or higher

   These provide support for the luxadm commands on the E3500.

2. Inform Volume Manager you wish to remove the disk

	vxdiskadm  option 4 (Remove a disk for replacement)

3. Take the disk offline

	vxdiskadm option 11 (Disable (offline) a disk device)

4. Remove the device entries, the following command will complete this

	luxadm remove_device <logical path or physical path or WWN ...>

5. Replace the disk, then

	luxadm insert  <no arguments required>
	or luxadm insert_device <logical path or physical path or WWN ...>

6. Inform Volume Manager of the new device

	vxdctl enable

7. Bring the disk back online

	vxdiskadm  option 5 (Replace a failed or removed disk)
