Archive Specific Parameters
- Type of archive media
- Select Tape, Magneto-Optical, Large Disk, or DVD (Linux only) to specify the type of archive device.
Tape
If you chose Tape, the following question appears:
- Device file
- Set the name of the device file for the tape. Note that this often takes the form of a name like /dev/rmt/c1t2d0. This means SCSI controller card 1, SCSI address 2, device 0.
Magneto-Optical
If you chose Magneto-Optical, the following questions appear:
- File system type
- Applicable to HP systems only. Set to HFS or VXFS to match your systems root file system type.
- Device file
- Set the name of the device file for the disk. Note that this often takes the form of a name like /dev/dsk/c1t2d0. This means SCSI controller card 1, SCSI address 2, device 0.
- MO Disk mount point
- Specify the point for the MO disk. The recommended value is /modisk, but any value could be used.
- Raw Device file
- Usually the same as the device file, but with a rdsk in the path.
Large Disk
If you chose Large Disk, the following question appears:
- LDA directory
- Specify the LDA directory, typically something like /usr/iris_data/lda1.
DVD
If you chose DVD (Linux only) the following questions appear:
- Device File
-
Specify the device file used for the DVD drive. Typically it looks something like /dev/scd0 or /dev/scd1.
You can determine this by typing as root
cdrecord -scanbus. Identify the entry for your DVD. The middle number of the leading group of 3 numbers identifies your device, for example, 3,0,0 corresponds to /dev/scd0 while 3,1,0 would be /dev/scd1. - DVD Disk mount point
- This is usually /mnt/dvd.
- Buffer Size
- To make the DVD writing more efficient, files are written to a temporary buffer called /usr/iris_data/temp/DvdArchive1 (for DVD 1). When the buffer size specified here is exceeded, then the files are written as a block to the DVD. During the write, IRIS "locks-out" sending new files to the buffer. After the files are written, the contents of the buffer are all deleted and the process repeats automatically. Files queued for send to the DVD are not lost. Note that the buffer is flushed to the DVD if IRIS is stopped (by qiris). Typical buffer size is 200 MB. DVD's can hold approximately 4 GB.
