FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks Director Release Notes (AA-RTDVH-TE, August 2005)

BB_Credit Allocati

on for ports

With ﬁrmware 0 7.00

.00 and later, this suppor ts the ability to allocate a speciﬁcnumber

of buffer credits per port. This feature provides beneﬁt primarily in the Edge Switch 2/12

and 2/24 switches, where a single pool of buffers is shared among all ports. Users

will now be able to allocate buffer credits only where needed. For the Director 2/64,

Director 2/140, and Edge Switch 2/32 switches, this enhancement simply allows m ore

granular conﬁguration options for users who want complete conﬁguration control.

NVR AM caching

All writes to n on-volatile memory random access memory (NV RAM), which stores

conﬁguration data, are now cached to prevent possible corruption of information. Prior

to ﬁrmware 0 7.00.00, a small windo w existed where a switch power-down during an

NVRAM write could enable the conﬁguration default settings when the switch is powered

back on. All switches and directors are now protected from p otential interruptions to

NVRAM updates.

Robust large fabrics

Numerous low-level enhancements and optim izations have been ma de to improve the

stability

of directors and switches in fabrics containing high populations of devices.

Changing password in CLI

When users are p rompted to change the password when logging into the Command Line

Interface (CLI), they can enter the d efault password (password). This will be accepted,

however at the next login they will again be required to change the password if it is

still the default password.

When users enter the default password when prompted to change the password, new

Security Log entry 10203, Default Password Not Changed,isposted.

Zoning

enhancement to reduce fabric congestion

In Homogeneous Fabric mode, an enhancement was added to reduce unnecessary

fabric congestion when performing fabric-wide zoning operations that impact the D efault

Zone. This enhancement limits the number of members allowed in the Default Zone to

64. When the ﬁrmware detects a zoning operation that would cause the member count

in the Default Zone to exceed 64 (such as deactivating an active zone set that has more

than 64 members), the op eration is aborted and the user interface (H AFM 8.6 or EWS)

dis

plays the following message: Zoning request denied: Operation will

cause the Default Zone to exceed its limit of 64 members.
