How to obtain device status connected to a IO board. Lets say for IO1 ?

Sc0:>Showdevices IO1

How to power on the domain Lets say A?

Sc0:> setkeyswitchd A on

How to power off the domain Lets say A ?

Sc0:> setkeyswitchd A off

How to make the domain A to standby ?

Sc0:>setkeyswitchd A standby

What will happen when the domain is at standby ?

The domain be down but the boards will remain in powered on state.

How to check the keyswitch status for domain A ?

Showkeyswitchd A

How to check the Openboot Prom variable of Domains from SC ?

Showobpparamsd A

If boards are using only one center plane then its called degraded mode. In normal mode all

extension boards will use both center planes

How to set to degraded mode ?

Setbusc CS0

How to set to normal mode ?

Setbusc CS0,CS1

How to check the bus status on all domains ?

showbus

How to power on the board from sc ?

Poweron SB0

How to power off the board from sc ?

Poweroff SB0

Is it possible to power off the domain with poweroff command while domain is active ?

No. The poweroff command will fail. To shutdown domain you have to issue command

setkeyswitchd A off

SMS supports how many types of blacklists ? What are they ?

Supports three types of blacklists

1. Platform blacklists -> /etc/opt/SUNWSMS/config/platform/balcklist

2. Domain blacklists -> /etc/opt/SUNWSMS/config/domain_id/blacklist

3. ASR(Automatic System Recovery ) Black lists

How to check the blacklists of Domain/Platform ?

How to reset the status of the components that has been set by ASR ?

setchs

What is the function of MAN ?

MAN ( MAnagement Network ) maintains private point-to-point network connections between the

SC's and each domain .

What is I1 network ?

The point-to-point network between domains and SC is called I1 network

What is I2 network ?

The point-to-point network between SC to SC is called I2 network

What type of network name would be plumbed on SC for I1 network ?

Scman0

What type of network name would be plumbed on SC for I2 network ?

Scman1

Does IP forwarding enabled in MAN ?

No. IP forwarding will be disabled by MAN

Lists few services that MAN network will be used for between sc and domains?

propagated. If required we have to manually propagate all files from main to spare.

How to forcibly propagate all the files from main to spare sc ?

Setdatasync backup

Through which network the file propagation will takes place ?

I2 network.

Does the network configuration Automatically propagates ?

No. we have to manually configure network using smsconfig -m

What is the HASram ? What's the function of it?

Its High-Availability Sram. This is used for communication between sc's apart from i2 network for
