Hi All!
Letīs say there are a few solaris servers connected to a NetApp storage device, but with no tape library or tape device attached to none of them. Assuming the O.S. is installed on the root disks, how to recover if the O.S. failed in one of the systems? Please share your ideas. (13 Replies)

rdump(8c) rdump(8c)
Name
rdump - file system dump across the network
Syntax
/etc/rdump [ -key [ argument ... ] filesystem ]
Description
The command copies to magnetic tapes, disks, or a dump image file all files changed after a certain date in the filesystem. The command is
identical in operation to except the f key must be specified and the file supplied should be of the following form:
remote-system-name:device-or-file
The command initiates a remote server, on the remote system to access the remote device or file.
Options
With the command, you specify a string of one or more of the options described below. If no options are specified, the key 9u is assumed.
0-9 This number is the ``dump level.'' All files that were modified since the last date stored in the file for the filesystem at
lesser levels will be dumped. If no date is determined by the level, the beginning of time is assumed. Thus, the level 0 causes
the entire filesystem to be dumped, a level 5 is used for a weekly backup and a level 9 for a daily backup.
B The next argument is a number that specifies the size, in 1024-byte blocks, of a storage medium, such as a diskette or a removable
disk. See the first example.
d The density of the tape, expressed in bits per inch, is taken from the next argument. This density is used in calculating the
amount of tape used per reel. The default density is 1600 bpi.
f Place the dump on the file or device specified by the next argument. This file is specified as remote-system-name:device-or-file.
n Notify, by means similar to a command, all users in the group ``operator'' when needs operator attention.
o Provides compatibility with non-ULTRIX or pre-ULTRIX Version 2.0 remote systems.
S Displays amount of space used by without performing the dump operation. This is used for presizing either for file preallocation
or to ensure the correct number of tapes or disks are on hand.
s The next argument specifies the size of the dump tape (in feet). When the specified size is reached, waits for the reel to be
changed. The default tape size is 2300 feet.
u If the dump completes successfully, writes the date of the beginning of the dump to file This file records a separate date for each
filesystem and each dump level. The format of consists of one free format record per line: filesystem name, increment level and
format dump date. The superuser can carefully edit to change any of the fields.
W The utility tells the operator what file systems need to be dumped. This information is taken from the files and The option causes
to print out, for each file system in the most recent dump date and level, and highlights those file systems that should be dumped.
If the option is used, all other options are ignored, and exits immediately.
w Unlike lists only those filesystems that need to be dumped.
Examples
This example reports number of bytes to be output for a level 0 dump of the root file system. Please note: the file is not created.
rdump OSf system:test /
This example dumps the root(/) file system from the local system to a remote system named ``nihil''. A level 0 dump to tape is performed
and the file is updated.
rdump 0uf nihil:/dev/rmt0h /
This example dumps the user (/usr) file system from the local system to a remote system named ``dickens'' using the RX50 device named for
output. A level 0 dump is performed, but the file is not updated.
rdump 0f dickens:/dev/rra1a /usr
This example dumps the root file system to a non-ULTRIX or ULTRIX before Version 2.0 remote system. A level 0 dump to a tape drive is per-
formed and the file is updated.
rdump 0ouf system:/dev/rmt0h /
This example dumps the root file system to a non-ULTRIX or ULTRIX before Version 2.0 remote system. A level 0 dump to the rx50 device is
performed and the file is updated. Note the specification of 400 as the device size in 1,024 byte blocks.
rdump 0ouBf 400 system:/dev/rra1a /
If you want to use / and you must have these entries in the file.
