If no NTP server is present, the date and time are maintained as if NTP had not been enabled. To manually set the system date and time: 1. Select Manage > General Config > Set Date/Time. 2. In the Set System Date panel, select the current month, day, and year. 3. In the Set System Time panel, type time values using a 24-hour clock (where hour 8 represents 8 a.m. and hour 20 represents 8 p.m.) and select the proper time zone. 4. Click Change Date/Time. To obtain the date and time from an NTP server: 1. Select Manage > General Config > Set Date/Time. 2. In the Obtain Time With NTP panel, set Network Time Protocol to Enable and optionally type the IP address of an NTP server. If no IP server address is set, the system listens for time messages sent by an NTP server in broadcast mode. 3. In the Set System Time panel, select the proper time zone. 4. Click Change Date/Time. You might have to refresh the page to display updated values from the NTP server. Creating Virtual Disks Two or more disk drives can be logically combined to form a virtual disk. The combined storage capacity can then be partitioned into volumes. SMU provides both manual and automatic methods for creating virtual disks, as described in its online help and in the reference guide. As an example, the following steps use the manual method to create two virtual disks with the following characteristics: ■ RAID 5, in which parity is distributed across all disk drives in the virtual disk ■ Five disk drives per virtual disk ■ One spare disk drive dedicated to each virtual disk ■ One volume per virtual disk, where the volume is not visible to data hosts 48 HP StorageWorks 2012sa Modular Smart Array user guide • May 2008

Creating Virtual Disks
Two or more disk drives can be logically combined to form a virtual disk. The
combined storage capacity can then be partitioned into volumes. SMU provides both
manual and automatic methods for creating virtual disks, as described in its online
help and in the
reference guide
.
As an example, the following steps use the
manual
method to create two virtual
disks with the following characteristics:
■
RAID 5, in which parity is distributed across all disk drives in the virtual disk
■
Five disk drives per virtual disk
■
One spare disk drive dedicated to each virtual disk
■
One volume per virtual disk, where the volume is not visible to data hosts
