Overview of the hd Utility
The Sun Fire X4500 Server supports 48 internal SATA drives. A physical map of these drives is located on the Sun Fire X4500 Server chassis label.
The hd utility is included in the SUNWhd package and is preinstalled on your server. The hd utility is a hard disk drive utility for the x86 systems, such as the Sun Fire X4500 Server. It is used to determine the logical-to-physical device mapping of your Sun Fire X4500 Server. You need to understand this mapping to administer the system, manage the hard drives, and troubleshoot the server.
The hd utility output enables you to locate all the disks visually based on the physical topology of the Sun Fire X4500 server drives by providing a color-coded hard drive location map. The utility’s output gives you a what-you-see-is-what-you-get (WYSIWYG) physical location map of the Sun Fire X4500 server’s drives. The hd utility provides the following features:
- Displays of all the available storage devices on the system
- Color-coded hard drive location maps
- Remote analysis
This utility has a run-time color mode to help you distinguish the status of a hard drive. It is a complementary tool to Solaris OS disk maintenance and configuration administration programs like format(1M) and cfgadm(1M). The hd utility output can also help you to identify which drives have not been enumerated. FIGURE 7-1 shows the Sun Fire X4500 server drive layout.

Using the hd Utility
To use hd utility you must have the hd package installed. This package is preinstalled in /opt/SUNWhd/hd/bin/hd. For additional commands related to hd, see the following man pages for additional commands: format(1M), cfgadm(1M), devfsadm(1M), and fdisk(1M).
hd Utility Mapping
You can use the drive mapping output from hd Utility for remote analysis. The utility also probes and displays all of the available storage devices in the system with their logical device name, serial number, vendor, model, and drive temperatures.
Here is sample output from the hd utility:

hd Command Options and Parameters
The hd utility makes a distinction between controllers, slots, and storage devices that are physically present in the machine and visible to the Solaris OS.
The hd command provides configuration and status information about the Sun Fire X4500 server’s hard drives by using specific command options and parameters. These options and parameters can be combined to display the information of your choosing. Some of the options available include displaying color mode (-c), summary, (-s), diagnose, (-d), identifying platform type, (-p), and obtaining configuration and status help messages (-h). FIGURE 7-3 shows a complete listing of hd Utility commands.

|
|
-d
|
Diagnoses the system by scanning the syslog (dmesg) for any disk’s warning messages. If there is a disk-related warning message, the utility maps the physical location of the drive with the ## warning message in the device status row. It appears in yellow if the -c option is used. It prints the disk warning message, which includes a timestamp indicating when the event happened.
|
|
-f
|
Allows you to specify any previous syslog file (usually the /var/adm/messages.n) with any disk warning messages.
|
|
-m
|
Maps the various possible pairs of drives for the Sun Fire X4500 server system. This command option is useful for testing drive-to-drive interaction from one drive to another drive in separate locations in the Sun Fire X4500 server. For performance, and other file system software, there are various ways to construct the pool of drives. This option provides distinct pairings based on the current probed logical and physical maps in the system. Supported map types are as follows:
|
|
|
|
Drive pairs that are on adjacent Marvell host controllers
|
|
|
|
Drive pairs that are on alternate Marvell host controllers
|
|
|
|
Drive pairs that are on the front and back rows
|
|
|
|
Drive pairs that are on diagonal locations
|
|
-w
|
Translates Solaris OSraw storage PCI device path to cXtY device name as used by most of the applications.
|
|
-h
|
Provides help.
|
|
-a
|
Lists the fdisk(1m) partition type. This option scans the disks for fdisk partitions that are recognized by x64 Solaris OS. Because the x64 platform also runs Linux and Windows, some of the disks could have non-Solaris fdisk partitions. For example, systems with dual booted operating systems.
|
|
-q
|
This option is for the Sun Fire X4500 server only.
It provides a list of Sun Fire X4500 hard drive physical slot numbers, logical names, and status (present or absent). This capability is useful for scripting environments. For example, some applications could include hd -q in noninteractive mode to determine if a specific drive in a specific physical slot is accessible before configuring RAID.
|
|
-l
|
Lists the Sun Fire X4500 accessible disks in sequential order. This option does not include the physical slot number.
|
|
-B

Sun Fire X4500 Disk Mapping
When you reinstall the OS, the hard disk names change depending on the ILOM version and USB CD storages devices present at the time of OS installation.
Pre-ILOM 2.0.2.5 and ILOM 2.0.2.5 and Later
The following applies to the hard drive and device mapping for systems with pre-ILOM 2.0.2.5 and ILOM 2.0.2.5 and later installed:
- Pre-ILOM 2.0.2.5: Remote CD-ROM is always mapped to c2 and remote floppy device is always mapped to c3.
- ILOM 2.0.2.5 or later: Remote CD-ROM and remote floppy devices are only mapped if enabled in the JavaRConsole. If one device is enabled, it will have the c2 number. If both are enabled, numbers c2 and c3 will both be used.
- Disk device path: /dev/cxtydz, where c is the Controller number, t is the target number, and d is the disk number.
- Channel numbers are assigned dynamically at the time of OS installation, and become static thereafter.
- Channel number assigning skips empty channels (controllers).
| Note - Only a fully populated system with all 48 disks is supported.
|
- Channel numbers change when a USB storage device is present at the time of OS installation.
- Solaris channel numbering with at least 1 HD per controller at install time:
- All disks on Controller 0 have a c0 number.
- All disks on Controller 1 have a c1 number.
- Remote USB devices, such as a CD-ROM or floppy, physically installed or present by mapping through JavaRConsole, will be inserted after Controller 1 and have numbers c2, c3, etc.
- All disks on Controller 2 will have a cx number, where x is 1+ the number of added USB devices. For example, on a system with 2 devices, Controller 2 will have a c4 name, and on a system with 3 devices, Controller 2 have a c5 name.
- All disks on remaining controllers will have a cx number where x is 1 more than the previous controller.

ILOM 2.0.2.5 or Later and One USB Device
When the ILOM version is 2.0.2.5 or later, the remote floppy and remote CD-ROM are now treated as USB storage devices and are only mapped when they are enabled in the javaRConsole. The channel numbers change depending on how many total USB storage devices are present at the time of OS installation. All USB devices gets enumerated between physical Controller 1 and Controller 2, which causes a shift in naming when compared to systems without any USB storage devices. For example, a USB DVD gets the c2 name and Controller 2 gets the c3 name:
