Release Notes 29

Known Issues

The following sections describe known issues for this release.

Persistent IP Address

Beginning with the J200 release, the IP address is persistent. The IP address is

stored on the midplane. When the controller is powered on, the firmware looks at

the IP address in the midplane and stores this address in the controllers flash

memory. When you replace a controller with a new controller, the new controller

will have the same IP address as the old controller.

In previous versions of the firmware, the IP address was only stored in the flash

memory of the controller. If it was necessary to replace a controller, you would have

to update the IP address of the new controller.

This causes an incompatibility between previous versions of the firmware and the

J200 firmware. When you upgrade to J200, the firmware looks at the midplane for

the IP address. If there is an IP address, that address is written to the controller’s

Flash memory. If the location of the IP address on the midplane does not contain a

valid IP address, then the IP address in the controller’s Flash memory is used. This

might cause you to lose connectivity during the upgrade process. As described in

“Updating RAID Controller Software” on page 10, you must connect directly to the

storage system in order to change the IP address.

Documentation Errata

■ In the CLI Reference Manual and in CLI help, descriptions of the CLI commands

scrub vdisk and verify vdisk incorrectly state that these commands

correct errors that they find. In fact, the number of inconsistencies found is only

reported in the "Vdisk verification complete" event (event code 21) in the event

log. Such inconsistencies can indicate that a drive in the virtual disk is going bad.

■ Similarly, in the Administrator’s Guide, the topic “Verifying a Virtual Disk”

incorrectly states that the Verify utility corrects errors that it finds. In fact, the

number of inconsistencies found is only reported in the "Vdisk verification

complete" event (event code 21) in the event log. Such inconsistencies can

indicate that a drive in the virtual disk is going bad.

■ Similarly, in the glossary, the definition of verify should state that errors are only

reported, not corrected.
