CHAPTER
1
The Sun Storage J4200/J4400 Array
The Sun Storage J4200 and J4400 arrays are general purpose, high-availability, and
cost-effective serial attached SCSI (SAS) devices. The J4200 is a 2U, 12-disk tray and
the J4400 is a 4U, 24-disk tray. Each supports SAS and Serial Advanced Technology
Architecture (SATA) disk drives. The main components in each array are hotswappable, including the SAS Interface Module (SIM) boards and drives, and the
dual load-sharing power supplies and fans, providing a fault-tolerant environment
with no single point of failure.
The J4200/J4400 arrays support 15K SAS drives and 7.2K SATA II drives. You can
interconnect up to four J4200/J4400 trays, with up to 48 drives in interconnected
J4200s and up to 96 drives in interconnected J4400s, all of which are designed to fit
into a standard 19-inch cabinet.
This renders a raw storage capacity of 14.4 TB for SAS disks (300 GB per disk) or 36
TB for SATA II disks (750 GB per disk) for the J4200, and 28.8 TB for SAS disks (300
GB per disk) or 72 TB for SATA II disks (750 GB per disk) for the J4400. Refer to the
Sun Storage J4200/J4400 Array Release Notes (820-3222-nn) for a complete listing of
supported drives.
The J4200/J4400 array is available for Solaris, Linux, Windows, and VMware
operating systems. You manage the array with the Sun StorageTek Common Array
Manager (CAM) software.
Note – If you are using the J4400 array as part of a Sun Storage 7000 Unified Storage
System, you do not manage the J4400 array using the Sun StorageTek Common
Array Manager (CAM). Instead, you manage the J4400 using the management
software provided with the Unified Storage System.
The trays can be installed into the following cabinets:
■ Sun Rack 900/1000 cabinet
■ Sun StorageEdge Expansion cabinet
■ Sun Fire Expansion cabinet
1
■ Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back
depth between vertical cabinet rails of 61 cm to 91 cm (24 in. to 36 in.). The
cabinet can have threaded or unthreaded cabinet rails.
The J4200/J4400 array can be delivered fully assembled or packaged as individually
ordered components that you install into the chassis. “Customer-Replaceable Units”
on page 24 provides a list of these components. All CRUs have a document
describing installation instructions.

J4200 Array Fan Modules
The fans circulate air inside the tray by pulling it through the vents on the front of
the assembly and pushing it out of the vents on the back of each fan.
Each J4200 array contains two hot-swappable fans for redundant cooling. Fan
Module 0 is on the left and Fan Module 1 is on the right. If one fails, the remaining
fan continues to provide sufficient cooling to operate the array. The remaining fan
runs at a higher speed until the failed fan is replaced. Replace a failed fan as soon as
possible.

Customer-Replaceable Units
The J4200/J4400 Array can be delivered fully assembled or packaged as individual
components that you install into the chassis. All customer-replaceable units (CRUs)
have a document describing the installation instructions in its shipping box.
Additionally, the Common Array Manager (CAM) software has a Service Advisor
application with wizards that guide you through CRU replacements.
The J4200/J4400 CRUs are designed for customers to install without turning off the
power, with the exception of the Chassis CRU, which by necessity must be shut
down and replaced by another chassis.
The following hardware components are designed to be customer installable:
■ SIM Board
■ Power Supply
■ Fan (J4200 only)
■ Disk Drives
■ Chassis
Management Software
The Sun StorageTek Common Array Manager (CAM) software suite provides
management, monitoring, and service capabilities. The software has both a browser
interface and a command-line interface (CLI).
24 Sun Storage J4200/J4400 Array System Overview • June 2009
The J4200/J4400 array requires a minimum version for CAM of 6.1.1. For detailed
information about which versions of CAM to use with the array, refer to the Sun
Storage J4200/J4400 Array Release Notes, part number 820-3222-xx, which is available
at the following location:
http://docs.sun.com/app/docs/prod/j4200.array
For complete CAM documentation, go to the following location:
http://docs.sun.com/app/docs/prod/stor.arrmgr
For more information about CAM, and to download the latest version, go to the
following location:
http://www.sun.com/storagetek/management_software/resource_management/cam/
Note – If you are using the J4400 array as part of a Sun Storage 7000 Unified Storage
System configuration, you do not use the CAM software suite. Instead, you manage
the array using the management software provided with the Unified Storage System.
Full Management Software
The full management software is installed on a management workstation. The
management software communicates with the J4000 arrays via a proxy agent that is
installed on the data host. It provides:
■ A browser interface
■ Multiple array management
Remote Proxy
The remote proxy agent enables communication, equivalent to in-band management,
from the full management host to the array over an out-of-band-band IP network.
Chapter 1 The Sun Storage J4200/J4400 Array 25
If the proxy is enabled, the full install of the Common Array Manager can manage
the J4000 Family array remotely. To use the browser interface to manage the J4000
Family array, you sign into the IP address or host name of the full management host,
sign into the software from the Java Web Console, and select the J4000 array. The
remote proxy must be enabled while running the installation wizard or script.
The remote proxy should not be enabled for directly connected arrays.
Command-Line Interface
The Sun StorageTek Common Array Manager software’s command-line interfaces
provide the same control and monitoring capability as the Web browser and it is
scriptable for running frequently performed tasks.
For more information about CLI commands, see the:
■ sscs man page

SAS Multipathing
You can use J4200/J4400 arrays in a serial-attached SCSI (SAS) multipathing
configuration. Multipathing provides higher availability by allowing data to use
multiple paths to the arrays from Host Bus Adaptors (HBAs) on the same server or
on different servers.
Multipathing capability resides in the operating systems running on the servers, not
on the J4200/J4400 arrays. You enable, disable, and configure multipathing through
the operating software.
This chapter includes the following information:
■ “System Requirements” on page 49
■ “Configuration Examples” on page 52
■ “Enabling and Disabling Multipathing in the Solaris Operating System” on
page 56

Enabling and Disabling Multipathing in
the Solaris Operating System
This sections describes how to enable and disable multipathing in the Solaris 10,
update 6, operating system.
Use the stmsboot command to enable multipathing in the Solaris 10, update 6,
operating system. stmsboot manages enumeration of multipath–capable devices
with multipathing; it has these characteristics:
■ Multipathing-enabled devices are enumerated under scsi_vhci(7D).
■ Multipathing-disabled devices are enumerated under the physical controller.
This section describes the stmsboot(1M) administration program for multipathing.
Device Renaming
In the /dev and /devices trees, multipathing-enabled devices receive new names
that indicate that they are under multipathing control.
■ This means a device has a different name from its original name (after enabling)
when it is under multipathing control.
■ The stmsboot command automatically updates /etc/vfstab and dump
configuration to reflect the device names changes when enabling or disabling
Multipathing.
■ One reboot is required for changes to take effect.
stmsboot Options
TABLE 5-3 describes the options supported by stmsboot(1M).
TABLE 5-3 stmsboot Options
-e [-D fp | mpt] Enables multipathing on all supported multipath-capable controller ports.
• Multipath-capable ports include SAS (mpt[7D]) controller ports.
• Prompts you to reboot.
• During reboot, vfstab and the dump configuration update to reflect the
device-name changes.
• Specifying -D mpt limits the enabling operation to ports attached using the
specified driver.
56 Sun Storage J4200/J4400 Array System Overview • June 2009
TABLE 5-3 stmsboot Options (Continued)
-d [-D fp | mpt] Disables multipathing on all supported multipath-capable controller ports.
• Multipath-capable ports include SAS (mpt[7D]) controller ports.
• Prompts you to reboot.
• During reboot, vfstab and the dump configuration update to reflect the device
name changes.
• Specifying -D mpt limits the disabling operation to ports attached using the
specified driver.
-u Updates vfstab and the dump configuration after manually enabling or
disabling multipathing on specific multipath- capable controller ports.
• Prompts you to reboot.
• During reboot, vfstab and the dump configuration update to reflect the
device name changes.
-L Displays the device name changes from non-multipathing-device names to
multipathing device names on multipath-enabled controller ports.
If multipathing is not enabled, no mappings display.
-l
controller_number
stmsboot Conditions
stmsboot enables and disables multipathing on the host, with these conditions:
■ The utility automatically updates vfstab(4) and dumpadm(1M) configuration to
reflect device-name changes.
Note – The system administrator is responsible for modifying application
configuration (for example, backup software, DBMS, and so forth) to reflect updated
device names.
■ The -L and -l options display the mapping between multipathed and non-
multipathed device names, only after changes to the multipathing configuration
take effect; that is, following reboot after invoking stmsboot -e.
■ ZFS datasets, including ZFS root datasets, are correctly handled by stmsboot.
Displays the device-name changes from non-multipathing device names to
multipathing device names for the specified controller.
If multipathing is not enabled, no mappings display.

TABLE 5-4 Load Balance Policies
Load Balance Policy Description
Fail Over Only The failover policy employs one active/optimized path and all other paths are
active/unoptimized, standby, or unavailable. The non-active/optimized paths
will be tried round-robin upon failure of the active/optimized path until an
available path is found.
Round Robin The round robin policy attempts to evenly distribute incoming requests to all
processing paths.
Round Robin with
Subset
The round robin with subset policy executes the round robin policy only on
paths designated as active/optimized. The non-active/optimized paths will be
tried on a round-robin approach upon failure of all active/optimized paths.
Least Queue Depth The least queue depth policy compensates for uneven loads by distributing
proportionately more I/O requests to lightly loaded processing paths.
Weight Paths The weighted paths policy allows the user to specify the relative processing load of each
path. A large number means that the path priority is low

Enabling and Disabling Multipathing in
the Linux Operating System
This section describes how to enable and disable multipathing in supported versions
of the Linux operating system.
▼ To Enable Multipathing in Linux
1. Attach a J4200 or a J4400 to a server with a supported version of Linux installed.
2. On the server, edit or create the /etc/multipath.conf file.
3. Reboot the server.
4. After the reboot, make sure that the OS discovers all the disks in the
J4200/J4400 arrays either by using the Linux commands, fdisk or lsscsi.
5. Partition any disks you want to the desired sizes.
6. Use the Linux command modprobe to add the loadable kernel modules dm-
multipath and dm-round-robin.
# modprobe dm-multipath
# modprobe dm-round-robin
Chapter 5 SAS Multipathing 77
7. Start the multipathd daemon.
For Linux SUSE 9, use the following command:
# multipathd -v0
For other supported Linux versions, use the following command:
# service multipathd start
8. Start the multipathing device mapper target autoconfig.
# multipath -v2
9. List the multipath devices that have been created.
# multipath -ll
The output should list the same number of devices as there are disks in the
J4200/J4400 arrays; it will look similar to the following:
35000c5000357625bdm-2 SEAGATE,ST340008SSUN0.4
[size=373G][features=0][hwhandler=0]
\_ round-robin 0 [prio=2][active]
\_ 0:0:0:0 sda 8:0 [active][ready]
\_ 1:0:0:0 sdm 8:192 [active][ready]
▼ To Disable Multipathing in Linux
1. If a RAID volume, LVM volume, or volume mount have been placed over the
device node of the multipathed disk, quiesce the volume.
2. Use the multipath -f command to disable multipathing to a specific device.
multipath -f mpath1
3. Use the multipath -F command to disable multipathing on all multipathed
devices.
multipath -F
Note – If the message map in use appears for a device when you attempt to
disable multipathing, the device is still in use. You must unmount or otherwise
quiesce the device before you can disable multipathing. If you cannot quiesce the
device, edit the /etc/multipath.conf file to exclude the device and then reboot
the server.
