MONITOR DISK DEVICES

With MONITOR DISK all available disk devices are monitored to check the available disk space and the disk error count. When the number of selected disk devices does not fit on one screen, the list of disk devices will be displayed in separate pages. After every interval period the next page will be displayed containing actual values. The default interval period is 60 seconds.

The selection of disk devices is based on Device Name, Allocation Device Name, Display Device Name or Full Device Name. Disk devices can also be selected based on the Volume Name and Media Type. MONITOR DISK can perform a REFRESH.

The display always contains a header with the Node Name (node where VIP runs), the Page Number, the number of selected disk devices and the current time. The information of every disk device is displayed in a separate line. Each line contains the Device Name, Volume Name, Media Type, total number of blocks, number of free blocks, free percentage, device error count en a combination of the following device characteristics: N(ot mounted), R(emote mounted), S(hadow set member), V(olume set member, with * is master disk) and W(rite locked).

When the available disk space of a device (in blocks or in percentage) comes under a specified limit, the corresponding line on the screen will be marked (displayed in bold, underlined, blinking or reverse video). This is also the case when the device error count increases or when a device is dismounted. All these situations may activate the ALARM.

When the ALARM has been activated because of a shortage of disk space, the SUBMIT can be activated. This causes a batch job to be started, that may contain user specified actions that clear the alarm condition, such as removing disk files. Parameters to the batch job can be the Device Name, the number of free blocks and the free percentage.
