Installation and conﬁguration best practices

• Install and con

ﬁgure your EVA4400 in the sequence listed in the installation guide. Several

installation

and conﬁguration steps include dependencies. Difﬁculties encountered by not

following the

the issues.

• When handling hard drives, follow industry-standard practices. Internal storage media can

be damaged when drives are shaken, dropped, or roughly placed on a work surface. When

removing a drive, press the release button, and then pull the drive only slightly out of the enclosure.

Then, to allow time for the internal disk to stop rotating, wait approximately 10 seconds before

completely removing the drive from the enclosure.

• If your env

ironment includes multiple servers, HP recommends designating one of the servers

as a management server, to centralize management tasks. It is on this server that you install

management software such as HP Command View EVA, and it is from this server that you

perform SAN management tasks.

• Assign static IP addresses to devices in the network.

• After con

ﬁguring the storage, remember to:

• Verify that each host has been granted access to the storage. Be sure to verify that all HBA

connections to the EVA are recognized, including all paths in a multipath conﬁguration. If all

connections from a host are not granted access, I/O cannot fail over to the redundant path.

• Limit access to the LUNs to prevent unintended or unauthorized access. Although not required,

HP stro

ngly recommends this security measure. These settings are especially important in

hetero

geneous environments to prevent servers running different operating systems and using a

mix of

HBAs from different vendors, from accessing the same LUN. For each HBA connection,

indicate the LUNs that it can access.

Ongoing best practices

• Proactively monitor EVA status and status changes via the HP Command View EVA

This software works in conjunction with other HP software to monitor and notify you of

possible issues. For additional information, see the HP Command View EVA website:

ttp://h18006.www1.hp.com/products/storage/software/cmdvieweva/index.html.

• Periodically check the EVA4400 website for updates and announcements.

• Schedule physical conﬁguration changes during periods of low or no activity in operational

environments. For example, if the system is performing rebuilds, array expansions, logical disk

extensions, or experiencing heavy I/O, avoid physical changes such as adding or replacing

disk drives.
