3.4.9 Event Log
Click “Event log” to view the event messages. Click “Filter” to select the log type to be displayed. Click
“Download” button to save the whole event log as a text fi le “qlog.txt”. Click “Clear” button to clear the
whole event log. Click “Mute” button to stop system alerts.
There are three methods to display the event log: “Show events” in the event log page, “Pop up events”
in the pop-up window in the web page, and “Show on LCM” (SR5650). You can select a preferred one. By
default, Warning and Error logs are shown on the web user interface and (SR5650).
3.5 Volume Confi g
“Volume confi g” function allows you to confi gure “Physical disk,” “Volume group,” “User data volume,”
“Cache volume,” and “Logical unit”.
3.5.1 Volume Relationship Diagram
The diagram above describes the relationship of RAID components. One VG (Volume Group) consists of a set of UDVs
(User Data Volume) and owns one RAID level attribute. Each VG can be divided into several UDVs. The UDVs from one
VG share the same RAID level, but may have different volume capacity. Each UDV will be associated with one specifi c
CV (Cache Volume) to execute the data transaction. Each CV could have different cache memory size as defi ned or
confi gured by user. LUN is the logical volume/unit, which could be controlled by user through SCSI commands.
3.5.2 Physical Disk
Enter the “Physical disk” option to view the status of hard disks installed in the system.
The following are operation tips:
1. Multiple selections. Select one or more hard disks by ticking the corresponding checkboxes. Or tick the checkbox
at the top left corner for the system to select all the disks automatically. Ticking again will select none.
2.
The list will not appear if there is no VG or only VG under RAID 0 or JBOD mode. This is because that
dedicated disk cannot be confi gured under these RAID levels.
3. These three functions, “Free disc”, “Global spares” and “Dedicated spares” also allow multiple selection.
4.
The operations of the other web pages (e.g., VG volume confi g, UDV, CV and LUN) are similar to above-
mentioned steps.
