Replacing a Disk Drive

NOTE Sometimes, the diskinfo and ioscan commands will produce cached data. To resolve this,

these commands should be run when the disk drive is removed.

Step 1. Visually inspect the replacement part for proper number and revision.

Step 2. Before installing the disk drive, type the following command:

#diskinfo -v /dev/rdsk/cxtxdx

Where cxtxdx = the device file of the disk removed.

Step 3. Then type the following:

#ioscan -f

The response message after running this command is:

NO_HW

Step 4. Ensure that the front locking latch is open, then position the disk drive in the chassis.

Step 5. Slide the disk drive into the chassis; apply slow firm pressure to properly seat the connection.

Step 6. Press the front locking latch to secure the disk drive in the chassis.

Step 7. Spin up the disk by entering one of the following commands:

#diskinfo -v /dev/rdsk/cxtxdx

Where cxtxdx = the device file of the disk removed.

#ioscan -f
