Step 7: Set up the mirrors for the root file system

Set up the mirrors for the root file system with the following steps:

1. Activate metadevice d11:

#metainit -f d11

d11: Concat/stripe is set up

#

2. Activate metadevice d13:

#metainit -f d13

d13: Concat/stripe is set up

#

3. Activate metadevice d12:

#metainit -f d12

d12: Concat/stripe is set up

#

4. Attach d12 to d13:

#metattach d13 d12

d13: submirror d12 is attached

#

5. Verify that root is set up and resynching:

#metastat d13 d13: Mirror

Submirror 0: d11 State: Okay Submirror 1: d12

State: Resyncing Pass: 1

Read option: roundrobin (default)

Write option: parallel (default)

Size: 2209680 blocks

.

.

.

Check the State: lines in the output list. They should read either Okay or Resyncing. If they do, then everything is fine. If they indicate any other status, something has gone wrong with the setup: discontinue the upgrade and telephone the Lucent National Customer Care Center (1.800.242.2121) or contact your Lucent representative or distributor.
