Hardware Issues and Workarounds

Booting Multiple Systems From a Single J4200 JBOD Storage Array

Sun Storage J4200 SAS JBOD arrays have six general-purpose SAS connectors. With FW version 3A32 or higher, each of them can be connected to separate SAS initiators, therefore up to six systems can be connected to the array. Each system can use a different disk on the array as its boot device. J4200 arrays have 12 disks, so each boot device can be mirrored for higher reliability. J4200 arrays can be configured into multiple zones to provide a more secure environment.

For related information, see Sun StorageTek Common Array Manager Software documentation, at:

Sun Crypto Accelerator 6000 Cards

If you are not using the correct version of the Sun Crypto Accelerator (SCA) 6000 card driver, hot-plug operations on SCA 6000 cards can cause M4000/M5000 servers to panic or hang. Version 1.1 of the SCA6000 driver and firmware supports hot-plug operations after the required bootstrap firmware upgrade has been performed. Version 1.0 of the SCA6000 driver does not support hot-plug and should not be used.

Do not hot-plug a Sun Crypto Accelerator (SCA) 6000 card into slot 1.

U320 PCIe SCSI Card

U320 PCIe SCSI card, part numbers 375-3357-01/02, is not supported in PCI cassettes for Sun SPARC Enterprise M4000/M5000 servers. Customers must use part number 375-3357-03 at a minimum.

Hardware Documentation Updates

This section contains important and late-breaking hardware information and corrections that became known after the documentation set was published.

	Section 4.4.3	“Powering the Server Off Manually” The corrected description has been updated in the manual.
	Section 8.2.2	“Installing the PCI Card” The corrected description and FIGURE 8-6, “Sequence of Fixing the PCI Card in Position,” has been updated in the manual.
	Section 11.2.1	“Confirmation of DIMM Information” The corrected description and FIGURE 11-5, “Example of DIMM Information,” has been updated in the manual.
	Section 12-2	“CPU Upgrades” The procedures have been added in the manual.
SPARC Enterprise M4000/M5000 Servers Installation Guide	Section 2.2.2	Table 2-3 “Power Cords” The following note will be added, Note - For servers that have the B-type plug, confirm that a 20A overcurrent protection device is available outside the server. If one is not available, prepare an external 20A overcurrent protection that can be achieved by means of no-fuse breakers (NFBs) or fuses. The B-type plug refers to plugs other than grounding-type ones with two parallel blades, such as the NEMA L6-30, L6-20, L6-15, and L5-15.
	Section 3.3.2	"Initializing the XSCF Unit" will be changed. See Initializing the XSCF Unit.

Initializing the XSCF Unit

Procedures for initializing the XSCF unit found in Section 3.3.2 of the Sun SPARC Enterprise M4000/M5000 Servers Installation Guide will be updated with the information below.

To use full XSCF functionality, various settings need to be set.

1. Set the required settings.

See section “Setting up XSCF” in the SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers XSCF User’s Guide for details on how to set these settings.

The following settings are required:

Registration of an XSCF user account and password and user privileges (adduser, password, setprivileges)

User account of a field engineer (FE) (for maintenance)

Date and time settings (setdate, settimezone)

Confirmation of XSCF host public key (showssh)

SSH/telnet settings (setssh, settelnet)

Network interface, routing, and DNS-related settings (setnetwork, setroute, setnameserver, etc.)

Note - Reset the XSCF unit with the applynetwork and rebootxscf commands.

Domain to Service Processor Communications Protocol (DSCP) configuration (setdscp)

Altitude setting (setaltitude)

Note - setaltitude must be followed by a rebootxscf to apply the altitude setting

Dual power feed option setting (setdualpowerfeed)

Note - setdualpowerfeed requires a complete chassis power cycle (all power cords removed) to apply any changes. Make certain to allow 30 seconds before plugging the power cords back into the chassis.

To perform XSCF initial settings, use the XSCF default user account. Until user accounts for user environment is registered, log in with a default user account and default password. The privileges of the default user are useradm and platadm.

2. Log in to the XSCF Shell using a user account and password set during Step 1.

See the SPARC Enterprise M3000/M4000/M5000/M8000/M9000 Servers XSCF User’s Guide for details on how to log in to the user account.
