These -may include tables and or graphs detailing statistics gathered from the -eraseblock data. Files are prefixed `analysis_'. - -See \fBANALYSIS\fR. -.IP "\-b, \-\-blocksize \fIblock\-size\fR" -Specify in bytes the \fIimage\-file\fR eraseblock size. Sizes may be -postfixed with `KiB' or `MiB' to indicate mebibytes or kibibytes -respectively. Default is 128KiB. -.IP "\-d, \-\-dir \fIoutput\-dir\fR" -Specify the output directory. If no directory is specified, the default -is `unubi_\fIimage\-file\fR' within the curent working directory. If the -attempt to create the output directory fails, -.B unubi -will try to create it in /tmp before aborting. -.IP "\-e, \-\-eb\-split" -When flagged, images are created for each eraseblock in \fIimage\-file\fR -regardless of its validity. Each image is the complete eraseblock, including -headers and any space to the end of the eraseblock after where the data may -end. - -Invalid images are named `ebEEEE', where EEEE is the physical index of the -eraseblock in the image. Valid images are named `ebEEEE_VVV_NNN_RRR' where -VVV is the known volume ID, NNN is the logical number and RRR is the version -of the eraseblock data. Note that the version number is in hexadecimal. - -Invalid images may also contain this postfix, if the data in the header -could be valid (ie. the header contains a resonable volume ID, but the -header and/or data CRCs are not valid). If this is the case, images are named -`ebEEEE_VVV_NNN_RRR.reason', so as to distinguish known values from -non\-definite ones. - -See \fBREASON SUFFIXES\fR. -.IP "\-r, \-\-rebuild \fIvolume\-id\fR" -Specify a volume to rebuild. Can be used successively to specify -several volumes to be rebuilt. - -Images are named `volumeVVV' where VVV is the volume ID. For each missing -eraseblock, an error message will be printed. -.IP "\-v, \-\-vol\-split" -When flagged, images are created for each valid eraseblock in -\fIimage\-file\fR. Since a vaild eraseblock will have a defined data start and -data length, only this range will make up the image. - -Images are named `volVVV_NNN_RRR_EEEE', where, for the data in the eraseblock, -VVV is the volume ID, NNN is the logical number, RRR is the version and EEEE -is the phyisical index of the eraseblock in the image. -.IP "\-V, \-\-vol\-split!" -Same as above, only all images are the complete eraseblock (including headers, -and raw data, even past the point where the data is supposed to end). -Overrides \-v when both \-v and \-V are flagged. -.SH ANALYSIS -The following files will be generated during the analysis: -.IP "analysis_ec_hdr.data" -A space delimited table with these two columns for each eraseblock: the -eraseblock's index or physical position in the image, and the eraseblock's -erase count. The third column contains the erase count data sorted. -.IP "analysis_vid_hdr.data" -A space delimited table with these four colums for each eraseblock: the -volume ID, the volume logical number, the leb version, and the data size. -In addition there are a normalized column representing the volume ID and -volume logical number, a normalized column representing the leb version, and -a normalized column representing the data_size. These normalized columns are -used to better draw the the gnuplot image. -.IP "analysis_ec_hdr.plot" -A gnuplot script for quickly viewing a sample output from the respective .data -file. -.IP "analysis_vid_hdr.plot" -A gnuplot script for quickly viewing a sample output from the respective .data -file. -.SH REASONS SUFFIXES -When \-\-eb\-split produces possibly invalid, though usable, eraseblocks, the -known reason suffixes are: -.IP ".ec_magic" -The erase counter header did not contain a valid magic field. -.IP ".ec_hdr_crc" -The erase counter header did not contain a vaild header CRC field. -.IP ".vid_magic" -The volume ID header did not contain a valid magic field. -.IP ".vid_hdr_crc" -The volume ID header did not contain a valid header CRC field. -.IP ".data_crc" -The volume ID header did not contain a valid data CRC field. -.SH EXAMPLES -To extract and rebuild all valid volumes from demo.img (note the output -directory will be /home/user/unubi_demo.img): -.sp 1 -.RS -.B /home/user# unubi demo.img -.sp 1 -.RE -To analyze demo.img as well as extract and rebuild volume 7: -.sp 1 -.RS -.B /home/user# unubi \-a \-r 7 demo.img -.sp 1 -.RE -To split demo.img into raw images for each eraseblock into the folder -/var/eraseblocks: -.sp 1 -.RS -.B /home/user# unubi \-e \-d /var/eraseblocks demo.img -.SH AUTHORS -Frank Haverkamp <haver@vnet.ibm.com> -.sp 0 -Drake Dowsett <dowsett@de.ibm.com> -.SH CONTACT -Andreas Arnez <arnez@de.ibm.com> |
