  • Create Cell Disk and Grid Disk Manually on Exadata

    We had a failed hard disk on a Exadata Storage cell X6-2. So we scheduled the Oracle Field Engineer to replace the bad disk. Oracle Field Engineer came onsite and replaced the faulty hard disk. Post hard disk replacement we found that the physical disk and luns are created successfully but the Cell disk and Grid disks were not created automatically. When a hard disk is replaced, the lun, cell disk and grid disks are created automatically and grid disks are added to ASM disk group for you without any manual intervention. In some odd cases, the Cell disk and grid disks are not created automatically, in those cases you must manually create the Cell disk, create the Grid disks with proper sizes and add them to the ASM disk group.


    In this article we will demonstrate how to create the Cell disk, Grid disks manually and add them to the respective ASM Disk Group.


    Environment

    • Exadata X6-2 Elastic Configuration
    • 4 Compute nodes and 6 Storage cells
    • Hard Disk Size: 8TB
    • 3 ASM Disk Group: DATA, RECO & DBFS_DG
    • Total Number of Grid disks: DATA – 72, RECO – 72 & DBFS_DG – 60

    Here the disk in the location 8:5 was back and replaced.


    Before Replacing Hard Disk:

    We can clearly see that the GRID DISKs are not present. So we have to create the GRID DISKs Manually.

    • Let’s try to create the Cell Disk

    [root@dm01cel03 ~]# cellcli -e create celldisk CD_09_dm01cel03 lun=0_5


    CELL-02526: Pre-existing cell disk: CD_09_dm01cel03


    It says the Cell Disk already exists.

    • Let’s try to create the Grid Disk. To create the Grid Disk with proper size, get the Grid Disk size from a good Cell Disk as shown below.

    [root@dm01cel03 ~]# cellcli -e list griddisk where celldisk=CD_07_dm01cel03 attributes name,size,offset
             DATA_CD_07_dm01cel03       5.6953125T              32M

    • Now create the Grid Disk

    [root@dm01cel03 ~]# cellcli -e create griddisk DATA_CD_05_dm01cel03 celldisk=CD_05_dm01cel03,size=5.6953125T


    CELL-02701: Cannot create grid disk on cell disk CD_05_dm01cel03 because its status is not normal.


    Looks like we can’t create the Grid Disk. We will now drop the Cell Disk and recreate it.

    The Grid Disks show active now. We can go ahead and add them to ASM disk Group Manually by connecting to ASM instance.


    • Log into +ASM1 instance and add the new disk.  Set the rebalance power higher (11) to perform faster rebalance operation.

    Conclusion


    In this article we have learned how to create the Celldisk, Griddisks and add the newly created Griddisks to ASM Disk Group. When a hard disk is replaced, the lun, celldisk and griddisks are created automatically and griddisks are added to ASM disk group for you without any manual intervention. In some cases, if the Celldisk and grid disks are not created automatically, then you must manually create them and add them to the ASM disk group.

  • Steps To Resize ASM disks in Exadata

    Overview
    In Exadata ASM disk groups are created from ASM disks which are provisioned as grid disks from Exadata storage cells. The grid disks are created from the celldisks. Normally, there is no free space in celldisks, as all space is used for grid disks, as shown below:

    [root@dm01cel01 ~]# cellcli -e “list celldisk where name like ‘CD.*’ attributes name, size, freespace”
             CD_00_dm01cel01         528.734375G     0
             CD_01_dm01cel01         528.734375G     0
             CD_02_dm01cel01         557.859375G     0
             CD_03_dm01cel01         557.859375G     0
             CD_04_dm01cel01         557.859375G     0
             CD_05_dm01cel01         557.859375G     0
             CD_06_dm01cel01         557.859375G     0
             CD_07_dm01cel01         557.859375G     0
             CD_08_dm01cel01         557.859375G     0
             CD_09_dm01cel01         557.859375G     0
             CD_10_dm01cel01         557.859375G     0
             CD_11_dm01cel01         557.859375G     0

    In this article I will demonstrate how to free up some space from the grid disks in RECO ASM disk group, and then reuse that space to increase the size of DATA disk group. The free space can be anywhere on the cell disks.

    Environment

    • Exadata Full Rack X2-2
    • 8 Compute nodes, 14 Storage cells and 3 IB Switches
    • High Performance Disks (600GB per disk)

    1. Free up space on celldisks
    Let’s say that we want to free up 50GB per disk in RECO disk group, we need to reduce the disk size in ASM, and then reduce the grid disk size in Exadata storage cells. Let’s do that for RECO disk group.

    We start with the RECO grid disks with the size of 268.6875G:

    [root@dm01cel01 ~]# cellcli -e “list grid disk where name like ‘RECO.*’ attributes name, size”
             RECO_dm01_CD_00_dm01cel01       105.6875G
             RECO_dm01_CD_01_dm01cel01       105.6875G
             RECO_dm01_CD_02_dm01cel01       105.6875G
             RECO_dm01_CD_03_dm01cel01       105.6875G
             RECO_dm01_CD_04_dm01cel01       105.6875G
             RECO_dm01_CD_05_dm01cel01       105.6875G
             RECO_dm01_CD_06_dm01cel01       105.6875G
             RECO_dm01_CD_07_dm01cel01       105.6875G
             RECO_dm01_CD_08_dm01cel01       105.6875G
             RECO_dm01_CD_09_dm01cel01       105.6875G
             RECO_dm01_CD_10_dm01cel01       105.6875G
             RECO_dm01_CD_11_dm01cel01       105.6875G

    To free up 50 GB, the new grid disks size will be 105.6875 G – 50 GB = 55.6875 GB = 57024 MB.

    2. Reduce size of RECO disks in ASM

    SQL> alter diskgroup RECO_dm01 resize all size 57024M rebalance power 32;

    Diskgroup altered.

    The command will trigger the rebalance operation for RECO disk group.

    3. Monitor the rebalance with the following command:

    5. Increase size of DATA disks in storage cells

    We can now increase the size of DATA grid disks, and then increase all disks size of disk group DATA in ASM.

    The current DATA grid disks size is 423 GB:

    [root@dm01cel01 ~]# cellcli -e “list grid disk where name like ‘DATA.*’ attributes name, size”
             DATA_dm01_CD_00_dm01cel01       423G
             DATA_dm01_CD_01_dm01cel01       423G
             DATA_dm01_CD_02_dm01cel01       423G
             DATA_dm01_CD_03_dm01cel01       423G
             DATA_dm01_CD_04_dm01cel01       423G
             DATA_dm01_CD_05_dm01cel01       423G
             DATA_dm01_CD_06_dm01cel01       423G
             DATA_dm01_CD_07_dm01cel01       423G
             DATA_dm01_CD_08_dm01cel01       423G
             DATA_dm01_CD_09_dm01cel01       423G
             DATA_dm01_CD_10_dm01cel01       423G
             DATA_dm01_CD_11_dm01cel01       423G

    The new grid disks size will be 423 GB + 50 GB = 473 GB.

    Resize the DATA grid disks on all storage cells. On storage cell 1, the command would be:

    8. Increase size of DATA disks in ASM

    SQL> alter diskgroup DATA_dm01 resize all rebalance power 32;

    Diskgroup altered.

    Note that there was no need to specify the new disks size, as ASM will get that from the grid disks. The rebalance clause is optional.

    The command will trigger the rebalance operation for disk group DATA.

    Monitor the rebalance with the following command:

    SQL> set lines 200
    SQL> set pages 200
    SQL> select * from gv$asm_operation;

    no rows selected

    Once the command returns “no rows selected”, the rebalance would have completed and all disks in disk group DATA should show new size:

    SQL> select name, total_mb/1024 “GB” from v$asm_disk_stat where name like ‘DATA%’;

    NAME                                   GB

    Conclusion

    In this article we have learned how to resize ASM disk in Exadata Database. If there is free space in Exadata cell disks, increasing the disk group size can be accomplished in two steps – grid disk size increase on all storage cells followed by the disk size increase in ASM. This requires a single ASM rebalance operation. If there is no free space in celldisks, some space may be freed up from other disk group. To reduce the size, first the ASM disk size is reduced and then reduced the grid disks size. To increase the size, first increase the grid disks size and the increase the ASM disk size.
