FW 6.4.0.06.00 McDATA 4Gb SAN Switch for HP p-Class BladeSystem Release Notes (AA-RW1ZD-TE, November 2006)

• When using the McDATA Web Server application, ensure that the switch has been removed from

the Selected Individual Addresses list in Discover Setup in HAFM, or alternatively that HAFM has

been closed and all services stopped prior to attempting the upgrade.

• When using the CLI, verify that the McDATA Web Server application is not open, and that the

switch has been removed from the Selected Individual Addresses list in Discover Setup in HAFM,

or that HAFM applications are closed and HAFM services stopped.

This single session limit is no longer an issue once you have loaded the ﬁrmware version 5.2.2.15.00

or later and attempted an NDCLA to a later release. Due to this limitation in the previous ﬁ rmware

versions, HP recommends that the switch ﬁrmware be upgraded to 5.2.2.15.00 or later prior to upgrading

the management applications.

Prior to upgrading ﬁrmware, HP recommends that you back up the switch conﬁguration in the event that

a failure should occur. Refer to “Backing up and restoring switch conﬁgurations” in the McDATA 4Gb

SAN Switch for HP p-Class BladeSystem user guide for more details.

If you attempt to perform a non-disruptive activation without satisfying the following conditions, the switch

may perform a disruptive activation:

• The current ﬁrmware version is a version that supports upgrading to the new version

• No changes are being made to switches in the fabric including powering up, powering down,

disconnecting or connecting ISLs, nameserver queries, and switch conﬁguration changes

• No port in the fabric is in the diagnostic state

• No zoning changes are being made in the fabric

• No changes are being made to attached devices including powering up, powering down,

disconnecting, connecting, and HBA conﬁguration changes

Ports that are stable when the non-disruptive activation begins and then change states, will be reset.

When the non-disruptive activation is complete, McDATA Web Server sessions reconnect automatically.

However, Telnet sessions must be restarted manually.

After upgrading ﬁrmware from 5.x.x.xx.xx to 6.4.0.06.00, any open Element Manager or McDATA Web

Server session will indicate that the ﬁrmware is not supported. This is simply an indication that the new

ﬁrmware is not supported by the current management session. To correct this, close the McDATA Web

Browser session and the browser window, or the Element Manager session. The unsupported ﬁrmware

message will not reoccur in subsequent McDATA Web Server or Element Manager sessions.

Installing ﬁrmware involves loading, unpacking, and activating the ﬁrmware image on the switch.

Activation of the ﬁrmware involves a hot reset to the switch, which is non-disruptive to attached devices.

During a hot reset operation, fabric services will be unavailable for a short period (30—75 seconds).

To ensure that a non-disruptive activation is successful, verify that all administrative changes to the

fabric (if any) are complete. When you need to upgrade ﬁrmware on multiple switches, only perform

the ﬁrmware upgrade on one switch at a time, and allow a 75 second wait prior to performing the

ﬁrmware upgrade on the next switch.

Con

siderations for downgrading the version of ﬁrmware

Dow

ngrading the version of ﬁrmware to previous ﬁrmware releases is a disruptive operation. Prior

downgrading ﬁrmware, attached devices should be prepared for disruption during the ﬁrmware

wngrade. Firmware on the McDATA 4Gb SAN Switch for HP p-Class BladeSystem cannot be

wngraded to a version earlier than 5.2.0.29.00. Prior to downgrading ﬁrmware,itisrecommended

hat you back up the switch conﬁguration in the event that a failure should occur. Refer to “Backing

p and restoring switch conﬁgurations” in the McDATA 4Gb SAN Switch for HP p-Class BladeSystem

ser guide for more details.
