V-filer & ISCSI

lagenevoise — Thu, 05 Jun 2025 06:52:31 GMT

Dear all Commuities Members,

I would like know if there is specifics limitations regarding number of Iscsi Connection onVfiler?

If my FAS is able to host N iscsi connection

Can I use all the connections for a specific Vfiler?

Does the max possible connections is the sum off all VFiler & Filer0 Iscsi Connections?

From Filer0 am I able to have the sum off all Vfiler Iscsi Connections?

I have read the vfiler.pdf from DOT 8.0.1 but few questions still be pending

Regards

Christophe.

hello,

i only know, that you can have 32 connections per session. you can change this value "options iscsi". i dont know if you can have this maximum of connection per vfiler.

The iscsi max ios and connections per session options are available in vfiler0 and not in vfilers. The setting in vfiler0 is for all vfilers.

VFILER CONSIDERATIONS

Each vfiler has its own set of options. Vfilers, however, recognize only a subset of the options recognized by a filer. The list of options recognized by a vfiler are:

cifs.audit.enable

cifs.audit.file_access_events.enable

cifs.audit.logon_events.enable

cifs.audit.logsize

cifs.audit.saveas

cifs.bypass_traverse_checking

cifs.comment

cifs.guest_account

cifs.home_dir_namestyle

cifs.homedirs_public_for_admin

cifs.idle_timeout

cifs.max_mpx

cifs.netbios_aliases

cifs.netbios_over_tcp.enable

cifs.nfs_root_ignore_acl

cifs.oplocks.enable

cifs.oplocks.opendelta

cifs.perm_check_ro_del_ok

cifs.perm_check_use_gid

cifs.preserve_unix_security

cifs.restrict_anonymous.enable

cifs.save_case

cifs.scopeid

cifs.search_domains

cifs.show_snapshot

cifs.shutdown_msg_level

cifs.sidcache.enable

cifs.sidcache.lifetime

cifs.snapshot_file_folding.enable

cifs.symlinks.cycleguard

cifs.symlinks.enable

cifs.trace_login

cifs.universal_nested_groups.enable

dns.domainname

dns.enable

ndmpd.access

ndmpd.authtype

ndmpd.connectlog.enabled

ndmpd.enable

ndmpd.ignore_ctime.enabled

ndmpd.password_length

nfs.mount_rootonly

nfs.per_client_stats.enable

nfs.require_valid_mapped_uid

nfs.tcp.enable

nfs.udp.xfersize

nfs.v2.df_2gb_lim

nfs.v3.enable

nfs.webnfs.enable

nfs.webnfs.rootdir

nfs.webnfs.rootdir.set

nis.domainname

nis.enable

nis.group_update.enable

nis.group_update_schedule

nis.servers

nis.slave.enable

pcnfsd.enable

pcnfsd.umask

rsh.access

rsh.enable

security.passwd.rules.enable

snapmirror.enable

snapmirror.checkip.enable

snapmirror.access

snapvault.access

snapvault.enable

wafl.default_nt_user

wafl.default_unix_user

wafl.nt_admin_priv_map_to_root

wafl.wcc_max_entries

wafl.wcc_minutes_valid

These options only affect the operation of the concerned vfiler. When run in the context of a vfiler, (e.g. via the vfiler run command), the options command only prints the options recognized by a vfiler, and can only change these options.

Hi Scott,

Thanks for your answer, I think I'm must clarify my question.

If I'm able to have a limitation of 256 Iscsi connections on a FAS.

Can I use all this connections for one Vfiler or I have a limitation per Vfiler (Dot 8.01.P5 FAS6240 HA)

regards

I dont' see anything in the documentation other than it is a vfiler0 (physical FAS) limit. It infers that the limit it on the physical system regardless of how it is split up across vfilers...so it should work on a single vfiler at that limit (but wouldn't have connections for other vfilers)... a physical system limit regardless of vfiler or not. Maybe someone from engineering (or if I missed somewhere in a TR or documentation) can post on this to confirm.
