With the command “hmc rmviosbk“ you can delete virtual I/O server backups from the HMC hard drive:

   hmc rmviosbk [-v] <hmc> <backup_selections>

The backup to be deleted must be specified as the only argument. For example, if the following backups currently exist on the HMC hmc01,

$ hmc lsviosbk hmc01
NAME              TYPE          SIZE      SYS_NAME  VIOS_NAME  LAST_MODIFIED
cfgbackup.tar.gz  viosioconfig  0.007     ms03      ms03-vio2  05/10/2024 08:57:41
fullbackup.tar    vios          3558.838  ms03      ms03-vio1  04/30/2024 12:05:00
fullbackup.tar    vios          6255.049  ms03      ms03-vio2  05/02/2024 08:56:55
$

and the backup cfgbackup.tar.gz of virtual I/O server ms03-vio2 should be deleted, then the name of the backup can simply be specified as an argument:

$ hmc rmviosbk hmc01 cfgbackup.tar.gz
$

Since there is only one backup with this name, the name is sufficient. However, if the fullbackup.tar of virtual I/O server ms03-vio2 is to be deleted, the name alone is not sufficient:

$ hmc rmviosbk hmc01 fullbackup.tar
hmc01: lsviosbk
USAGE:
   hmc rmviosbk [-v] <hmc> <backup_selections>
ERROR: 'fullbackup.tar' matches more than one backup:
did you mean: fullbackup.tar
did you mean: fullbackup.tar
$

There are two backups named fullbackup.tar, one for ms03-vio1 and one for ms03-vio2. Therefore, the name alone is not enough to clearly select the desired backup.

The problem can be solved by simply specifying the name of the virtual I/O server (see selections):

$ hmc rmviosbk hmc01 fullbackup.tar,ms03-vio2
$

Alternatively, you could have specified size=6255.049 as an argument, since there is only one backup with this size:

$ hmc rmviosbk hmc01 size=6255.049
$

Instead of selecting the backup to be deleted using many selections, it is often easier to use the analogous command “vios rmviosbk”.
