Replacing a failed bootdisk

In the following example, the host has a failed bootdisk (c0t0d0). Fortunately, the system is using DiskSuite, with a mirror at c0t1d0. The following sequence of steps can be used to restore the system to full redundancy.

System Fails to Boot

When the system attempts to boot, it fails to find a valid device as required by the boot-device path at device alias "disk". It then attempts to boot from the network:

screen not found

Can't open input device

Keyboard not present. Using ttya for input and output.

Replace failed disk and restore redundancy

The administrator replaces the failed disk with a new disk of the same geometry. Depending on the system model, the disk replacement may require that the system be powered down. The replacement disk is then partitioned identically to the mirror, and state database replicas are copied onto the replacement disk. Finally, the metareplace command copies that data from the mirror to the replacement disk, restoring redundancy to the system.

If there is messages like this :

Jan 14 05:05:15 osssvr picld[241] : Device PS1 unplugged
Jan 14 05:05:16 osssvr picld[241] : Device PS1 Plugged in

Then

indicates a power supply is inserted but the AC power cord is not plugged in.

so please as soon as the AC power cord is plugged in.

note : environment monitoring of a power supply occurs only if the power cord is plugged in.
