These release notes describe the following topics:
 |
Note Before attempting to connect the Cisco Storage Array to a Cisco Cache Engine model 570, be sure to upgrade the CE 570 to software version 2.1.3 or a more recent version, (see the section, "Upgrading to a New Software Release"). |
|
Note The most current Cisco documentation is on Cisco Connection Online (CCO). The electronic documents may contain updates and modifications made after the hardcopy documents were printed. |
The Storage Array is a rack-mounted, just a bunch of disks (JBOD) hard disk array and enclosure that interfaces with host systems through an Ultra2 LVD SCSI bus. The backplane can be configured as two buses to serve two host systems or as a single bus to provide more drive and disk capacity to a single host.
The Storage Array enclosure supports up to six hard disk drives, two power supply modules (AC or DC), and three fan modules. The system includes a Versatile Environmental Monitor (VEM) that monitors enclosure temperature, power supplies, and cooling fan status.
Of all the models of the Cisco Cache Engine 500 Series, the Storage Array can operate to specification only with the Cisco Cache Engine 570. The Cache Engine 570 must run software release 2.2.0 or a more recent version.
|
Note Cisco recommends that you install the most recent software version available for your Cache Engine. |
To determine the version of the software currently running on the Cisco Cache Engine 570, log on and enter the show version EXEC command.
Cache Engine software can be downloaded from the Cisco Systems Software Center at the
following URL:
http://www.cisco.com/cgi-bin/tablebuild.pl/cache-engine
Presently, two types of Cache Engine software files are available on CCO to download, files with the .pax suffix and files with the .bin suffix. The .pax file contains the full-image software with the GUI and is the file routinely installed. The .bin file software is for recovery situations that require booting from the network, or restoring Flash memory. Refer to the section "Recovering the Cache Engine System Software" in the Cisco Cache Engine User Guide for instructions on loading your system image with the .bin file.
Step 2 Log on to the Cache Engine, and at the command prompt, enter:
install filename.pax
where filename is the name of the .pax file
Step 3 Follow the command line interface instructions as prompted.
Step 4 After the Cache Engine has rebooted, use the show version command to display the current
software version.
Refer to the software documentation and software release notes of the host that you are connecting to the Storage Array for partition, format, mounting, and maintenance instructions.
The I/O module does not support the daisy-chain mode configuration of multiple Storage Array units as described on pages 1-3, 4-5, and 4-8 of the Cisco Storage Array Installation and Configuration Guide. Future revisions of the I/O module hardware will support daisy-chain mode configurations and have a different part number. The I/O modules are field-replaceable.
To prevent data corruption, make sure to tighten all jack screws on the SCSI cable at both the server and the Storage Array ends. Avoid bumping or twisting SCSI cables connected to the
Very High Density Cable Interconnect (VHDCI) SCSI connectors on the Storage Array I/O module.
Replace the section, "I/O Module Insertion and Removal," in Chapter 3 of the Cisco Storage Array Installation and Configuration Guide with the following section:
The I/O module is housed in a device carrier to allow for easy insertion and removal. To insert or remove the I/O module, use the supplied shuttle key to turn the lead screw.
|
Note The lead screw plug is a plastic piece that fits over the end of the lead screw to prevent the lead screw from loosening when vibrated. |
Step 2 Slide the I/O module carefully into the far left bay of the Storage Array (bay 0) until you feel resistance.
Step 3 Fit the shuttle key over the end of the lead screw as shown in Figure 3-3.

Step 4 Turn the shuttle key clockwise until the I/O module is seated correctly.
Step 5 Remove the shuttle key and place the lead screw plug over the end of the lead screw.
The I/O module is now ready for use.
 |
Caution Before removing an I/O module, ensure that all I/O activity of the Storage Array has ceased. |
Step 2 Disconnect all SCSI cables connected to the I/O module.
Step 3 Remove the lead screw plug and replace it with the shuttle key.
Step 4 Turn the shuttle key counterclockwise until you feel no resistance.
Step 5 Remove the shuttle key.
Step 6 Slide the I/O module carefully out of the Storage Array.
Step 7 Place the lead screw plug over the end of the lead screw.
The following documents provide supporting information concerning the operation and installation of the Cisco Storage Array:
