Restoring from a CMSADM Backup

This section contains the procedure for restoring /cms data files from a traditional CMSADM backup tape.

You may want to perform a CMSADM restore when, for example, your file systems are still intact, but some data has been corrupted.

If your CMS is running on a Sun Enterprise 3500, and you have had a crashed or corrupted disk, check the /kernel/drv/st.conf file before you begin the restore. Make certain the file contains the following entry:

#Begin CMS tape configuration list. tape-config-list=

"EXABYTE EXB-8900", "Mammoth EXB-8900 8mm Helical Scan", "EXB-8900",

"TANDBERG TDC 4200", "Tandberg 2.5 Gig QIC", "TAND-25G- FIXED",

"TANDBERG SLR5", "Tandberg 8 Gig QIC", "TAND-8G-FIXED"; EXB-8900 = 1,0x29,0,0xce39,4,0x7f,0x7f,0x7f,0x7f,0; TAND-25G-FIXED = 1,0x37,512,0x867a,1,0x00,0;

TAND-8G-FIXED= 1,0x37,512,0x963a,4,0xA0,0xD0,0xD0,0xD0,3;

#End CMS Tape configuration list.

If the file does not contain the entry, add it. The 3500’s Mammoth 8mm tape drive will not operate if the entry is absent.

To restore a CMSADM backup, do these steps:

1.Obtain the latest CMSADM backup tape.

2.Load the backup tape into the tape drive.

3.Enter the following command:

# cpio -icmudv -C 10240 -I <device>

where <device> is one of the following:

/dev/rmt/0 The internal, noncompressing tape drive (14-GB, 8-mm drive) with the lowest target address.

/dev/rmt/1 The external, noncompressing tape drive (QIC-150 or 5-GB, 8-mm drive) with the second lowest target address.

/dev/rmt/0c The internal, compression-capable tape drive (usually a 14-GB or 40-GB) with the lowest target address.

/dev/rmt/1c The external, compression-capable tape drive (either a QIC 2.5-GB or a 14-GB tape drive) with the second lowest target address.
