We like to use the results of the PRTERRLOG TYPE(*VOLSTAT) to predict when we'll need another tape cartridge in our drive to perform the backup. However, it seems that some items can apparently write much more data to the cartridge. I suspect that it depends on the compressibility of the data. I combined all the output from our various boxes to one report: Volume ---Temporary Errors--- --------M Bytes-------- ID Read Write Read Written SFRI11 0 0 1 336537 GFRI11 0 0 1 22664 WFRI11 0 0 1 18984 DFRI11 0 0 1 283125 DFRI21 0 0 1 155981 HFRI11 0 0 1 220831 6FRI1 0 0 1 223611 6FRI2 0 0 1 223913 6FRI3 0 0 1 223380 6FRI4 0 0 1 210898 01WK2 0 0 1 117170 02WK2 0 0 1 110359 03WK2 0 0 1 105878 04WK2 0 0 1 112585 05WK2 0 0 1 114559 06WK2 0 0 1 65112 All backups except for the ??WK2 set were done to 3582 LTO2 tape drives. The ??WK2 was done to a 3581 LTO1 tape drive. The S* backup was from a combination of libraries and IFS objects on our development partition on the 520. The G* backup was from a combination of libraries and IFS objects on a little test 270 that's hardly ever used. The W* backup was from a combination of libraries and IFS objects on a partition on our 570 that is mostly Domino. The D* backup was from Domino IFS objects on our busy partition on our 570. The H* backup was all of our BPCS, payroll, and some IFS objects other than Domino on our busy partition on our 570. The 6FRI* backup was a SAVOBJ of some huge highly compressed objects in a library created by the old ADSM (being phased out by TSM on this machine) Problem statement: How can I tell when the S* backup will need another tape cartridge? 6FRI* backup SAVOBJ does the following: Library Object SIZE Object Object Type Attribute PCBACKUP PCBACKUP00 262,209,286,144 *FILE PF PCBACKUP PCBACKUP01 262,209,286,144 *FILE PF PCBACKUP PCBACKUP06 104,884,985,856 *FILE PF PCBACKUP PCBACKUP07 52,445,650,944 *FILE PF PCBACKUP PCBACKUP11 52,445,650,944 *FILE PF PCBACKUP PCBACKUP12 52,445,650,944 *FILE PF PCBACKUP PCBACKUP02 52,443,553,792 *FILE PF PCBACKUP PCBACKUP03 52,443,553,792 *FILE PF ...
