Add Disks to FASTT700

[DebiJo]

My apologizes for what I suspect is a very stupid question....

I have a FASTT700 hooked to 2 AIX Risc/6000 servers. I have 5 drawers for disks, most have empty slots. I have purchased additional disk drives.

Can I just slide the drives in hot?

I know what to do on the AIX side (a reboot or a cfgmgr) to see the disks. I'm just a little paranoid about the act of putting the new disks physically in the drawer.

Thanks in advance,
Debi

Hi Debi,

Unix *is* user friendly. It's just selective about who its friends are.

I would not add the drives without running the Disable Drive Migration script that comes with Storage Manager.
Be careful as the script will reset both controllers.

1. Run disabledrivemigration.scr
2. Add your drives to the EXP's
3. Run enabledrivemigration.scr

While you can do this live I would not do it on a busy production server during peak hours.



disabledrivemigration.scr

// Show the current state of Drive Migration 

show "Showing the current state of Drive Migration (80=Off, 82=On)"; 

show controller[a] nvsrambyte[0x35]; 

show controller[b] nvsrambyte[0x35]; 

//

// Setting Drive Migration to Disable 

show "Setting Drive Migration to Disable"; 

set controller[a] nvsrambyte[0x35] = 0x02,0x02; 

set controller[b] nvsrambyte[0x35] = 0x02,0x02; 

show controller[a] nvsrambyte[0x35]; 

show controller[b] nvsrambyte[0x35]; 

//

// To prevent the controllers from restarting, add ?//? to the beginning 

// of each of the lines below. This will comment out the restart of the

show "Resetting controller A"; 

reset Controller [a]; 

show "Resetting controller B"; 

reset Controller [b]; 

//

show "Drive Migration is now disabled. Add the new drives to the subsystem,";

show "then execute the EnableDriveMigrationScript.scr to re-enable drive ";

show "migration.";

enabledrivemigration.scr

// Show the current state of Drive Migration 

show "Showing the current state of Drive Migration (80=Off, 82=On)"; 

show controller[a] nvsrambyte[0x35]; 

show controller[b] nvsrambyte[0x35]; 

//

// Setting Drive Migration to Enable 

show "Setting Drive Migration to Enable";

set controller[a] nvsrambyte[0x35] = 0x02,0x00; 

set controller[b] nvsrambyte[0x35] = 0x02,0x00; 

show controller[a] nvsrambyte[0x35]; 

show controller[b] nvsrambyte[0x35]; 

//

show "Resetting controller A"; 

reset Controller [a]; 

show "Resetting controller B"; 

reset Controller [b]; 

show "Drive Migration is now enabled.";
