NAME

dr_cmd_a_attach - abort DR attach system board operation

SYNOPSIS

dr_cmd_a_attach sb

AVAILABILITY

Sun Enterprise 10000 servers only.

DESCRIPTION

Caution:

Do not use this command, which runs in the DR shell; it is included here only for completeness. Instead, use abort_attach(1M), which performs the same functions, but with the added security of safeguards and checks.

If abort_attach(1M) were unavailable for some reason, you could run dr_cmd_a_attach after a system board has been successfully init attached via dr_cmd_init_attach(1M) and before the board has been completely attached via the dr_cmd_c_attach(1M). dr_cmd_a_attach returns the board to the state it was in prior to the dr_cmd_init_attach(1M) operation; that is, present, powered-on, and in no domain.

dr_cmd_a_attach instructs the operating system running on the target domain to abandon the in-progress attach operation, removes the system board from the domain_config file, and resets the Enterprise 10000 server's centerplane shared memory mask registers and board domain mask registers.

Some conditions that are transparent to the user may cause an abort failure. Therefore, if dr_cmd_a_attach fails to complete the abort successfully, try executing it again at a later time.

OPTIONS

sb

The system board number (0 to 15) for the abort attach operation.

EXIT STATUS

If dr_cmd_a_attach succeeds it returns a 0 result code in the dr_return global variable. If it fails, it returns a 1 and displays diagnostic messages.

Note:

Tcl parsing errors prevent DR commands from running which, in turn, leaves dr_return uninitialized. In such cases, the dr_return error code is meaningless. See dr (1M)for more information concerning return codes.

DIAGNOSTICS

See DIAGNOSTICS on abort_attach(1M).
