Wildcards in SAN Allow and Deny Lists
After configuring
allowList
and denyList
for SAN
transport mode, customers requested a wildcard mechanism for ease of use. VDDK 8.0.1 and
later support wildcards to simplify list making. You can use meta character expressions * ?
[xyz] [a-z] [0-9] with the same meanings as in Bash shell. In case of duplicates or ambiguity,
vixDiskLib.transport.san.allowlist
takes precedence over vixDiskLib.transport.san.denylist
. Wildcards
match neither directory separator slash (/) nor folder separator backslash (\). On
Windows, deny and allow lists must contain "\\?\"
or
"\\.\
prefix, and sharp (#)
must be inside double-quotes to avoid interpretation as a comment;
PhysicalDrive
"allowList="\\?\scsi#disk*"
for example. Metacharacters | Examples of wildcard use |
|---|---|
* | Match the preceding character
or subexpression zero or more times, for example /dev/* matches
/dev/, /dev/ab, and /dev/cde |
? | Match any single
character, for example /dev/sd? matches
/dev/sda and /dev/sdb |
[a-z] | Match a character in the
specified range, for example /dev/test[1-2]
matches /dev/test1 and /dev/test2 |
[xyz] | Match any character included
in the set, for example /dev/sd[abc]
matches /dev/sda, /dev/sdb, and /dev/sdc |
Example of allow and deny lists for
Linux:
vixDiskLib.transport.san.denylist="/dev/sd*" vixDiskLib.transport.san.allowlist="/dev/sd[a-f]"
Example of allow and deny lists for
Windows:
vixDiskLib.transport.san.allowlist="\\?\scsi#disk&ven_scst_bio&prod_disk[1-3]*" vixDiskLib.transport.san.denylist="\\?\scsi#disk&ven_scst_bio&prod_disk4*"
