Upgrade Drives on an M-Series Appliance

1. Access the command line interface (CLI) on the M-Series appliance.
   Connect to the M-Series appliance in one of two ways:

   • Connect a serial cable from your computer to the Console port and connect to the M-Series appliance using terminal emulation software (9600-8-N-1).
   • Use terminal emulation software (such as PuTTY) to open a Secure Shell (SSH) session to the IP address of the M-Series appliance.
2. When prompted, log in to the appliance.
   Use the default administrator account and the assigned password.
3. Verify that the RAID 1 status for the installed drives shows there are at least two functioning RAID 1 arrays. During the upgrade, you will upgrade one RAID 1 array at a time and there must be at least one other RAID 1 array that is available to the appliance. The appliance will show an abort error if you try to remove the only functioning array from the configuration.
   Enter the following command to view RAID status:

   > show system raid detail

   For example, the following shows an output from an M-500 appliance with two available arrays (Disk Pair A and Disk Pair B). If there is only one available array, you must add a second array as described in Add Additional Drives to an M-Series Appliance before you upgrade the drives.

   Disk Pair A                           Available 
      Status                                 clean 
      Disk id A1                           Present 
          model        : ST91000640NS 
          size         : 953869 MB 
          status       : active sync 
      Disk id A2                           Present 
          model        : ST91000640NS 
          size         : 953869 MB 
          status       : active sync 
   Disk Pair B                           Available 
      Status                                 clean 
      Disk id B1                           Present 
          model        : ST91000640NS 
          size         : 953869 MB 
          status       : active sync 
      Disk id B2                           Present 
          model        : ST91000640NS 
          size         : 953869 MB 
          status       : active sync 

4. Remove the first 1TB drive and replace it with a 2TB drive.
   1. To remove the first drive from the RAID 1 array configuration (A1 in this example), enter the following command and enter y when prompted to confirm the request:

      > request system raid remove A1

   2. Physically remove the first drive from the drive bay. Press the ejector button on the drive carrier in drive bay A1 to release the ejector handle. Then pull the handle toward you and slide the drive out of the appliance.
   3. Remove a 2TB drive from its packaging and place the drive on a table next to the drive you just removed. Take note of how the drive is installed in the carrier because you will install the 2TB drive in this same carrier.
   4. Remove the four screws holding the 1TB drive in the carrier and remove the drive from the carrier.
   5. Attach the 2TB drive to the carrier using the same four screws you removed from the 1TB drive and then reinsert the carrier with the 2TB drive into drive bay A1.
   6. Enter the following command to verify the 2TB drive is recognized:

      show system raid detail

      Verify that the A1 disk shows the correct model and size (about 2TB). If the model and size are not correct, run the above command again until the correct model and size are shown.

      If the wrong model and size are consistently shown, enter the following command:

      request system raid remove A1

      Wait for 30 seconds once you run the above command, then remove the disk and reinsert it and repeat the show system raid detail command to verify the size and model.
5. Copy the data from the remaining installed 1TB drive in the RAID 1 array to the newly installed 2TB drive in that array.
   The time required to copy the data may vary from several minutes to a few hours, depending on the amount of data on the drive.
   1. To copy the data from the 1TB drive in drive bay A2 to the newly installed 2TB drive in drive bay A1, enter the following command and enter y when prompted:

      > request system raid copy from A2 to A1

   2. To view the status of the copy process, run the following command:

      > show system raid detail

      Continue running this command to view the RAID detail output until you see that the array (A1/A2 in this example) shows Available.

      At this point, drive A2 will show not in use because there is a drive size mismatch.
6. Upgrade the second drive in the RAID 1 array to a 2TB drive.
   1. Remove the second 1TB drive (from drive bay A2 in the current example) for the RAID 1 array configuration:

      > request system raid remove A2

   2. Insert the carrier with the newly installed 2TB drive into drive bay A2 and add it to the RAID 1 array configuration:

      > request system raid add A2

      The system will copy the data from A2 to A1 to mirror the drives.
   3. To view the status of the copy process, run the following command:

      > show system raid detail

      Continue to view the RAID detail output until you see that the array (A1/A2 in this example) shows Available and both disks show active sync.

      Disk Pair A       Available 
         Status         clean 
         Disk id A1     Present 
             model        : ST2000NX0253 
             size         : 1907138 MB 
             status       : active sync 
      Disk id A2     Present 
             model        : ST2000NX0253 
             size         : 1907138 MB 
             status       : active sync 

7. Upgrade drives for additional RAID 1 arrays as needed.
   To upgrade additional RAID 1 arrays to 2TB drives, repeat this procedure replacing the drive designators as applicable. For example, replace A1 with B1 and A2 with B2 to upgrade the drives in the B1/B2 RAID 1 array.
