Table 4-3 lists the functionality provided by the Disk Information window.

Table 4-3 Disk Information Window Functionality


Field	Functions
Device name	The device name, for example, `c2t1d0`.
Status	The status is reported as OK, Reserved if the disk is reserved by another host, Failed, or Spun Down if this is a SPARCstorage Array disk and it is spun down.

Device Statistics Window

The Device Statistics window, shown in Figure 4-11, displays a "snap-shot" of statistical information about a specific metadevice or physical disk. There are two ways to display this window:

Select a metadevice on the Metadevice Editor window's canvas, or a disk on the Disk View canvas, by pointing to it and pressing the SELECT button. Select Statistics from the Object menu.

The menu button to the right of the field enables you to specify the units used. The values on the menu are Gbytes, Mbytes, Kbytes, and Sectors. The default is Kbytes. After the Custom field is complete, the Attach button is used to assign the interlace value to the stripe. After a stripe is committed, the interlace value cannot be changed.
Show Slices	This toggle button enables you to turn on and off the slice manipulation region. The number of slices in the stripe are shown in parentheses on the button.
Slice manipulation region	The following functionality is available in this region: Scrolling List - Shows slices included in the stripe. The information in this region includes the name of the slice, size, number of state database replicas on the slice, and the status. Enable - Enables the selected slices if they are disabled. Remove - Removes the selected slices. Slice - Specifies a new slice to be attached to the stripe or replaces the selected slice. If no slice is selected, the button is unavailable. Attach - Attaches the slice specified in the Slice field to the stripe. This button is active only when a slice name is entered in the field. Replace - Replaces the selected stripe with the slice entered in the Slice field. This button is active only when a slice name has been entered in the field and a slice is selected on the scrolling list. Info - Displays the Slice Information window for the selected (highlighted) slice.

Mirror Information Window

DiskSuite provides several options to optimize mirror performance. These options deal with the read and write policy for mirrors, and the order in which mirrors are resynced during reboot. You set these and other options using choices on the Mirror Information window, as shown in Figure 4-14. There are three ways to display the Mirror Information window:

Double-click the mirror object in the Objects list. The mirror is opened on the Metadevice Editor's canvas. Select Info from the Objects menu.
If the mirror object is on the Metadevice Editor's canvas, point inside the mirror rectangle. Press and hold down the MENU button to display the pop-up menu then select the Info option.
If the mirror object is on the Metadevice Editor's canvas, double-click inside the mirror rectangle.

Figure 4-14 Mirror Information Window

The Mirror object must be committed before the policy changes take effect.

Table 4-9 lists the functionality associated with the regions of the Mirror Information window.

Table 4-9 Mirror Information Window Functionality


Field	Functions
Device Name	The metadevice name of the mirror. As long as the device is not "open," you can change the name by typing a new one and clicking Attach.
Status	Description of the mirror's status.
Size	The total size of the mirror.
Use	Shows how the mirror is currently used, for example, file system, swap, or shared log. If the use is shared log, a button labeled Show Trans is displayed. The Show Trans button opens a Sharing Information window that shows the Trans devices that share the Mirror.
Show Submirrors	This toggle button enables you to turn on and off the submirror manipulation region. The number of submirrors in the mirror are shown in parentheses on the button.
Pass	A pass number in the range 0-9 can be assigned to a mirror using the Pass button menu. The pass (resync) number determines the order in which that mirror is resynced during a system reboot. The default is 1. Smaller pass numbers are resynced first. If 0 is chosen, the resync is skipped. A 0 should only be used for mirrors mounted as read-only. If different mirrors have the same pass number, they are resynced concurrently.
Read Option	There are three kinds of read options associated with mirrors: Round Robin, Geometric, and First. The default read option is Round Robin, also called balanced load. When set to Round Robin, all reads are made in a round robin order from all the submirrors in the mirror. That is, the first read comes from the first submirror, the next read comes from the second submirror, and so forth. The Geometric option provides faster performance on sequential reads or when you are using disks with track buffering. Geometric reads allow read operations to be divided among submirrors on the basis of a logical disk block address. For instance, with a three-way mirror the disk space on the mirror is divided into three (equally sized) logical address ranges. Reads from the three regions are then performed by separate submirrors (for example, reads to the first region are performed by the first submirror). The First option specifies reading from only the first submirror. This would be specified only if you have a second submirror that has poor read I/O characteristics.
Write Option	A button that enables you to set parallel or serial writes to the submirror. Parallel writes are the default action of the metadisk driver, meaning the writes are dispatched to all submirrors simultaneously. Serial writes specify that writes to one submirror must complete before the next submirror write is started.
Submirror manipulation region	The following functionality is available in this region: Show Submirrors - This toggle button enables showing or hiding the list of submirrors. Scrolling List - Shows submirrors included in the mirror. The information in this region includes the name, type, size, and status. Click on the submirror to select it. When submirrors are selected, actions can be performed on them. Online - Brings selected submirrors back online. This button is active only when the selected submirror is offline. Offline - Takes selected submirrors offline. This button is active only when the selected submirror is online. Remove - Detaches the selected submirrors. Info - Opens the Concat Information window for the selected submirror. Device - Specifies a new submirror in the field to attach or replace. The field is cleared when you click on the Attach or Replace buttons. Attach - Adds the specified submirror. This button is active only when a submirror or device is entered in the Device field. Replace - Replaces the selected submirror with the submirror entered in the field. This button is active only when a submirror or device is entered in the field and one in the list is selected.

Trans Information Window

The Trans Information window enables you to view and modify the attributes and components of a specific trans metadevice. Figure 4-15 shows the Trans Information window. There are three ways to display the Trans Information window:

Double-click the Trans object in the Objects list. The object is opened on the Metadevice Editor's canvas. Select Info from the Objects menu.
If the Trans Metadevice object is on the Metadevice Editor's canvas, point inside the Trans rectangle. Press and hold down the MENU button to display the pop-up menu then select the Info choice.
If the Trans Metadevice object is on the Metadevice Editor's canvas, point inside the Trans rectangle and double-click.
