Updating Firmware; Selecting An Appropriate Time To Perform The Online Upgrade; Setting The Date And Time - HP AA988A - Modular Smart Array Storage Controller SCSI User Manual

Updating Firmware

After installing the hardware and powering up the enclosure for the first time, be
sure to verify that the controllers and drive enclosures have the latest firmware.
SMU enables you to view the software, hardware, and other version information for
each controller and the enclosures.
To view controller version information, select Monitor > Status > Advanced
Settings > Controller Versions. To view drive enclosure information, select Manage
> Update Software > Enclosure Firmware > Show Enclosures.
Selecting an Appropriate Time to Perform the
Online Upgrade
To ensure the success of an line upgrade, selecting the appropriate time is essential.
Selecting a period of low I/O activity will ensure the upgrade completes as quickly
as possible, and will avoid disruptions to host and applications due to timeouts.
Attempting to upgrade a storage system that is in the middle of processing a large
I/O intensive batch job will likely cause hosts to lost connectivity with the storage
system. Consequently, finding an appropriate time for the upgrade is very important.
For software and firmware updates, go to
MSA SAN Arrays, select your product, and go to Support.
For detailed steps on updating the firmware, see the reference guide.

Setting the Date and Time

You can set the date and time manually or configure the system to use Network
Time Protocol (NTP) to obtain them from a network-attached server. When NTP is
enabled, and if an NTP server is available, the system time and date can be obtained
from the NTP server. This allows multiple storage devices, hosts, log files, and so
forth to be synchronized.
NTP server time is provided in Universal Time (UT), which provides several
options:
If you want to synchronize the times and logs between storage devices installed
■
in multiple time zones, set all the storage devices to use UT.
If you want to use the local time for the device, select the appropriate time zone.
■
If a time server can provide local time rather than UT, configure the storage
■
devices to use that time server, with no further time adjustment.
