Safety notices and their translations

Safety notices are printed in English throughout this document.

A Danger notice warns you of conditions or procedures that can result in death or severe personal injury.

A Caution warns you of conditions or procedures that can cause personal injury that is neither lethal nor extremely hazardous.

An Attention notice warns you of conditions or procedures that can cause damage to machines, equipment, programs, or data.

For translations of the danger and caution notices, see Expandable Storage Plus 2104 Model DS4 and Model TS4 Translated Safety Notices, SC26-7558. The notices are listed in numeric order based on their IDs, which are displayed in parentheses, at the end of each notice. See the following examples of danger and caution notices for the location of the ID number.

DANGER

An electrical outlet that is not correctly wired could place a hazardous voltage on the metal parts of the system or the products that attach to the system. It is the customer’s responsibility to ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (1)

CAUTION:

Do not insert hands or tools into the opening of the empty space that contained the fan assembly. (1)

Electrostatic discharge (ESD)

Attention: When you handle field-replaceable units (FRUs) and other computer

parts, take these precautions to avoid static damage:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Always touch the computer parts carefully. Hold the cards by their edges or metal

cover. Never touch any exposed circuits.

v Prevent people who are not correctly grounded from touching computer parts.

v Before you install a new part, touch the static-protective package that contains

the part against an unpainted metal part of the 2104 Model DS4 or host system for at least 2 seconds. This reduces the static electricity in the package and in your body.

v Remove the part from its package and, if possible, install it directly into the 2104

Model DS4 without putting the part down. If you must put the part down, follow these steps:

1. Place the static-protective package that contained the part onto a smooth, level surface.

2. Place the part onto the static-protective package. Do not place the part directly onto any metal surface.

power cables for the 2104 Model DS4 are connected.

Notes:

1. Each rack-mounted 2104 Model DS4 requires an airflow of 1.1 m³ per minute (40 ft³ per minute). When racks containing many 2104 Model DS4s are to be installed together, the following requirements must be met to ensure that the 2104 Model DS4s are adequately cooled:

v The airflow enters at the front of the rack and leaves at the back. To prevent

the air that is leaving the rack from entering the intake of another piece of equipment, racks should be positioned in alternate rows, back-to-back and front-to-front.

v The front of the racks should be positioned on floor-tile seams, with a full line

of perforated tiles immediately in front of the racks. Each perforated tile should have an air flow of at least 11.34 m³ per minute (400 ft³ per minute). The temperature under the floor must not exceed 15°C (60°F).

v Where the racks are in rows front-to-front or back-to-back, there should be a

gap of at least 1220 mm (48 in.) separating the rows.

v To ensure correct air flow within each rack, the rack filler plates must be

installed in unused positions. Also, all the gaps in the front of the racks must be sealed, including the gaps between the 2104 Model DS4s.

2. Maintain the operating temperature at 22°C (72°F) or lower.

The timing sequence of disk motor startup is under the control of the host system software.

SC000011

Figure 34. Setting the option switches

When the drive autostart switch-1 1 is set to on and the drive autostart switch-2 2 is set to off, the disk drives are set to delay motor start mode. The disk motor startup delay time is different for each disk drive, and is usually computed by multiplying its SCSI ID by 12 seconds. For example, the disk drive motor of a disk drive with a SCSI ID equal to 2 will start 24 ( 2 x 12) seconds after power is applied to the 2104 Model DS4.

When the drive autostart switch-1 1 is set to off, and the drive autostart switch-2 2 is set to off, the disk drives are set to normal start mode. The disk drive motors will start when power is applied to the 2104 Model DS4.

The effect of both this switch and the drive autostart switch-2 2 being set to on is undefined.

5. To set the drive autostart switch-2 2, see step 4 for an explanation about the drive autostart switch-1 1.

6. Ensure that the enable enclosure services switch 3 and the select enclosure services switch 4 are both set to on to allow ANSI SCSI-3 Enclosure Services (SES) to operate. This applies to both AIX and Linux users. Your Linux operating system might not support SES, but the SES functions are used when running the standalone AIX Diagnostics CD.

7. When the power control switch 5 is set to off, the 2104 Model DS4 automatically switches off or on when the host system is switched off or on. When this switch is set to on, the 2104 Model DS4 is powered on or off by the dc on/standby switch on a fan-and-power-supply assembly.

10. The SCSI bus split control 7 controls the SCSI bus mode. When the switch

is off, the enclosure is configured as a single SCSI bus. When this switch is on, the enclosure is configured as a dual or split SCSI bus.

11. Verify that switch 8 and 9 (reserved) are off.

12. Verify that the disable ID 6 handling switch 10 is off. The SCSI ID 6 is

automatically disabled and removed from the system when the following conditions are met:

v The switch is off.

v Two SCSI interface cards are installed with single-bus configuration.

v Two hosts are connected to the 2104 Model DS4 and both are on.

When you install two SCSI Interface cards and you configure the 2104 Model DS4 for single-bus mode, an ID conflict occurs if you install a drive in the slot of SCSI ID 6. The ID conflict exists because one of the host bus adapter (HBA) SCSI IDs should be set to 6 when using both host ports. Unless the disable ID 6 handling switch is off or the drive is removed from the slot of SCSI ID 6, there will be an ID conflict between the HBA that is using ID 6 and the drive in the slot of SCSI ID 6. Removing the drive from slot 6 and replacing it with a dummy carrier eliminates the conflict.

An alternative is to turn the disable ID 6 handling switch off, which continuously applies a SCSI RESET signal to the drive in the slot of ID 6 when TERMPWR is present on both JBOD interface cards. While the drive is held in RESET, it releases all bus signals, effectively removing it from the system. The drive in the slot of SCSI ID 6 will continuously remain in RESET under these conditions until power is removed and the disable SCSI ID 6 handling switch is on.

Identifying a 2104 Model DS4 and the disk drive modules

You can identify a 2104 Model DS4 and the disk drive modules installed in it by running either AIX or Linux.

Refer to the 2104 Interoperability Matrix link located at the following Web site

Note:

to learn which versions of AIX or Linux are supported for the Expandable Storage Plus family of products.

www.storage.ibm.com/disk/expplus/supserver.htm/

AIX

When running AIX, you can identify an 2104 Model DS4 and the disk drive modules installed in it either by the location code contained in system messages that refer to that unit, or by using the SCSI Device Identification and Removal service aid.

For more information, see the section about location codes in the operator guide for your system.

Linux

When running Linux, you can identify an 2104 Model DS4 and the disk drive modules installed in it by using the List Configuration command. Consult your Linux operating system documentation for information on how to use this command.

Configuring a 2104 Model DS4 to an AIX host system

Use the cfgmgr command to configure or reconfigure a 2104 Model DS4 to the host system.

This command might not be valid for your RAID adapter.

Note:

Unconfiguring a 2104 Model DS4 from an AIX host system

To remove a 2104 Model DS4 from the host system, use the following command:

rmdev -l [enclosurenumber] -d

where [enclosurenumber] is the enclosure device that was generated by the cfgmgr command (for example, [ses0], [ses1], [ses2]).

Remove the ses_healthcheck job from the system cron table.

Configuring a 2104 Model DS4 in a SuSE Enterprise Server for pSeries environment

In general, SuSE Enterprise Server for pSeries systems are automatically configured during initial start up or restart up. See the SuSE Enterprise Server for pSeries documentation for more information.

Collecting Errors

Note: Collecting errors through the cron job is only available on systems that are

running AIX.

To collect enclosure errors, add this cron job SES Healthcheck to the system cron table.

Note: Yo u must have root permissions to complete this procedure.

the system crons with the crontab -e command. At the bottom of the file, enter:

Edit

15 * * * * /usr/lpp/diagnostics/bin/run_ses_healthcheck 1> /dev/null 2> /dev/null

For more information about the crontab command, see the following Web page:

http://publib16.boulder.ibm.com/pseries/en_US/cmds/aixcmds1/crontab.htm

This cron runs at 15 minutes after each hour, and e-mails the root user with details of any errors in the enclosure. It also presents a console message that indicates which enclosure has a problem. The cron requires a script. To create this script, generate a file named run_ses_healthcheck in the /usr/lpp/diagnostics/bin directory.

The contents of the file must be:

#!/bin/ksh #Name: run_ses_healthcheck #Location: /usr/lpp/diagnostics/bin #Function: SCSI SES hourly healthcheck for i in `lsdev -Cc container -t ses -s scsi -F name -S available` do

diag -cd $i > /dev/null if [ $? -ne 0 ] then

done

/usr/lpp/diagnostics/bin/diagrpt -o > /tmp/ses.health.output # you may want to process the output prior to placing it in # a file. # somehow notify the user of the error. A sample is shown # below. mail -s ’2104 Health Check’ root < /tmp/ses.health.output

rm /tmp/ses.health.output

This command runs the script:

chmod 544 /usr/lpp/diagnostics/bin/run_ses_healthcheck

Appendix B. Cable configurations

This appendix shows examples of cable configurations for the 2104 Model DS4. Some of the configurations are valid for all the adapters that the 2104 Model DS4 or Model TS4 supports. Other configurations are valid only for particular types of adapters. Also shown are configurations that are invalid. Do not use any configuration that is shown as invalid; unexpected results might occur.

Valid configurations

Only point-to-point connections are allowed between the SCSI interface cards in a 2104 Model DS4 and the SCSI adapter card or integrated SCSI port in a host system.

A 2104 Model DS4 with only one SCSI interface card can be attached to one SCSI adapter or integrated SCSI port. A 2104 Model DS4 with two SCSI interface cards can be attached to two SCSI adapters or integrated SCSI ports.

When you use an internal connector on the adapter card, do not use the corresponding external connector to connect to a 2104 Model DS4.

A 2104 Model DS4 can be configured to support either a single SCSI bus or a dual SCSI bus. The setting of the SCSI bus split switch on the card in the 2104 Model DS4 defines which configuration is to be used.

An RS/6000 or IBM Eserver pSeries computer uses one of the following SCSI adapters to connect to the 2104 Model DS4:

v PCI Dual-Channel Ultra3 SCSI adapter (type number 4-Y, feature code 6203)

This dual-channel adapter has two external SCSI connectors and two internal SCSI connectors. Each pair, consisting of one external and one internal connector, is connected to a separate SCSI channel.

v PCI 4-Channel Ultra3 SCSI RAID Adapter (type number 4-X, feature code 2498)

This 4-channel adapter has four external SCSI connectors and two internal SCSI connectors. The Channel 1 and Channel 2 external connectors share the same SCSI bus as the corresponding Channel 1 and Channel 2 internal connectors. The Channel 3 and Channel 4 external connectors have their own non-shared SCSI bus.

v PCI-X Dual Channel Ultra320 SCSI adapter (type number 5702, feature code

5712)

This dual-channel adapter has two external SCSI connectors and two internal SCSI connectors. Each pair, consisting of one external and one internal connector, is connected to a separate SCSI channel.

v PCI-X Dual Channel Ultra320 SCSI RAID Adapter (type number 5703, feature

code 5703)

This dual channel adapter has two Ultra320 SCSI busses, each with one internal and one external connector.

An IBM Eserver pSeries computer running Linux on pSeries uses one of the following SCSI adapters to connect to the 2104 Model DS4:

v PCI-X Dual Channel Ultra320 SCSI Adapter (type number 5702, feature code

5712)

v PCI-X Dual Channel Ultra320 SCSI RAID Adapter (type number 5703, feature

Single-bus mode configurations

For a single-bus mode configuration, the SCSI bus split switch on the card of a 2104 Model DS4 must be set to off.

Each 2104 Model DS4 can be connected to one external SCSI connector on a SCSI adapter card, or to one integrated SCSI port, in a host system. If an adapter card has four external SCSI connectors, it can be connected to up to four 2104 Model DS4s.

For High Availability Cluster Multi-Processing (HACMP) configurations, the two SCSI interface cards in a 2104 Model DS4 are connected either to external SCSI connectors on adapter cards, or to integrated Ultra2 SCSI ports, in two different host systems. The adapter cards must be a PCI Dual-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203) or PCI-X Dual Channel Ultra320 SCSI adapter (type number 5702).

For non-HACMP configurations, the SCSI interface cards in a 2104 Model DS4 can be connected either to an external SCSI connector on an adapter card, or to an Ultra2 SCSI integrated port, in a host system. Each adapter must be a PCI Dual-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203) or PCI-X Dual Channel Ultra320 SCSI adapter (type number 5702). The adapters must be in two different host systems. They must not share access to the disk drives in the 2104 Model DS4.

2. In each 2104 Model DS4, slots 6 and 7 (SCSI addresses 5 and 6) must contain dummy disk drive modules.

3. Each 2104 Model DS4 can contain no more than 12 disk drive modules.

44 Expandable Storage Plus 2104 Model DS4 Installation Guide

Dual-bus mode configurations

For a dual-bus mode configuration, the SCSI bus split switches must be set to on.

Each 2104 Model DS4 in the configuration is connected either to one external SCSI connector on an adapter card, or to an integrated SCSI port. If an adapter card has four external SCSI connectors, it can be connected to up to four 2104 Model DS4s.

The external SCSI connectors can be either on the same adapter card, or on two separate adapter cards. If the connectors are on two separate adapter cards, these adapter cards can be either in the same host system or be in two separate host systems.
