2.3.3.3 Shrink the Grid Disks in the Donor Disk Group

After shrinking the disks in the Oracle ASM disk group, you then shrink the size of the grid disks on each cell.

This task is a continuation of an example where space in the RECOC1 disk group is being reallocated to the DATAC1 disk group.

You must have first completed the task Shrink the Oracle ASM Disks in the Donor Disk Group.

1. Shrink the grid disks associated with the RECO disk group on all cells down to the new, smaller size.

   For each storage cell identified in Determine the Amount of Available Space in Step 3, shrink the grid disks to match the size of the Oracle ASM disks that were shrunk in the previous task. Use commands similar to the following:

   dcli -c exa01celadm01 -l root "cellcli -e alter griddisk RECOC1_CD_00_exa01celadm01 \
   ,RECOC1_CD_01_exa01celadm01 \
   ,RECOC1_CD_02_exa01celadm01 \
   ,RECOC1_CD_03_exa01celadm01 \
   ,RECOC1_CD_04_exa01celadm01 \
   ,RECOC1_CD_05_exa01celadm01 \
   ,RECOC1_CD_06_exa01celadm01 \
   ,RECOC1_CD_07_exa01celadm01 \
   ,RECOC1_CD_08_exa01celadm01 \
   ,RECOC1_CD_09_exa01celadm01 \
   ,RECOC1_CD_10_exa01celadm01 \
   ,RECOC1_CD_11_exa01celadm01 \
   size=282672M "
   
   dcli -c exa01celadm02 -l root "cellcli -e alter griddisk RECOC1_CD_00_exa01celadm02 \
   ,RECOC1_CD_01_exa01celadm02 \
   ,RECOC1_CD_02_exa01celadm02 \
   ,RECOC1_CD_03_exa01celadm02 \
   ,RECOC1_CD_04_exa01celadm02 \
   ,RECOC1_CD_05_exa01celadm02 \
   ,RECOC1_CD_06_exa01celadm02 \
   ,RECOC1_CD_07_exa01celadm02 \
   ,RECOC1_CD_08_exa01celadm02 \
   ,RECOC1_CD_09_exa01celadm02 \
   ,RECOC1_CD_10_exa01celadm02 \
   ,RECOC1_CD_11_exa01celadm02 \
   size=282672M "
   
   ...
   
   dcli -c exa01celadm14 -l root "cellcli -e alter griddisk RECOC1_CD_00_exa01celadm14 \
   ,RECOC1_CD_01_exa01celadm14 \
   ,RECOC1_CD_02_exa01celadm14 \
   ,RECOC1_CD_03_exa01celadm14 \
   ,RECOC1_CD_04_exa01celadm14 \
   ,RECOC1_CD_05_exa01celadm14 \
   ,RECOC1_CD_06_exa01celadm14 \
   ,RECOC1_CD_07_exa01celadm14 \
   ,RECOC1_CD_08_exa01celadm14 \
   ,RECOC1_CD_09_exa01celadm14 \
   ,RECOC1_CD_10_exa01celadm14 \
   ,RECOC1_CD_11_exa01celadm14 \
   size=282672M "

2. Verify the new size of the grid disks using the following command:

   [root@exa01adm01 tmp]# dcli -g cell_group -l root "cellcli -e list griddisk attributes name,size where name like \'RECOC1.*\' "
   
   exa01celadm01: RECOC1_CD_00_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_01_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_02_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_03_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_04_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_05_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_06_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_07_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_08_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_09_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_10_exa01celadm01 276.046875G
   exa01celadm01: RECOC1_CD_11_exa01celadm01 276.046875G  
   ...

   The above example shows that the disks in the RECOC1 disk group have been resized to a size of 282672 MB each (276.046875 * 1024).
