Depending on the size of the disks, the system may run slowly until all disks are synchronized.

Administering replacement data disks, R3V9 and later

If a data disk drives fails, you must follow the recovery procedures as outlined in “Recovering a non-mirrored system after data disk failure” in the Maintenance chapter of the software installation, maintenance, and troubleshooting document for your version of CMS.

2.Verify that the disk has been partitioned.

3.Enter:

df -k /cms

The percentage of total space that CMS is currently occupying is displayed, as in the following example:

# df -k /cms

Note the capacity percentage (in this example, 11%). The capacity used by /cms will be smaller after a new disk is added.

4.Enter the following commands to set the path variables:

PATH=$PATH:/usr/opt/SUNWmd/sbin:/olds export PATH

5.Check the disk partitioning by entering the following commands: olds -check_disks cxtydz

where cxtydz is the device name of the disk that you added (for example, c0t1d0).
