Hi All,
I'm preparing to migrate some servers from vscsi to pass-thru NPIV. I am planning to have the SAN team move the exact LUNs from vio1/vio2 to those two VWWN through NPIV.
My question is on the partition itself.. right now, let's say I have hdisk0/1/2/3/4 that are part of datavg. They... (2 Replies)

Hi,
I want to change from vscsi to npiv. Is it possible to use both on the same adapter, so we can change the systems one by one, or must we place a second FC adapter in the VIO servers?
Thanks,

stablerestart
STABLERESTART(5) BSD File Formats Manual STABLERESTART(5)
NAME
nfs-stablerestart -- restart information for the NFSv4 server
SYNOPSIS
nfs-stablerestart
DESCRIPTION
The nfs-stablerestart file holds information that allows the NFSv4 server to restart without always returning the NFSERR_NOGRACE error, as
described in the NFSv4 server specification; see Network File System (NFS) Version 4 Protocol RFC 3530, Section 8.6.3.
The first record in the file, as defined by struct nfsf_rec in /usr/include/fs/nfs/nfsrvstate.h, holds the lease duration of the last incar-
nation of the server and the number of boot times that follows. Following this are the number of previous boot times listed in the first
record. The lease duration is used to set the grace period. The boot times are used to avoid the unlikely occurrence of a boot time being
reused, due to a TOD clock going backwards. This record and the previous boot times with this boot time added is re-written at the end of the
grace period.
The rest of the file are appended records, as defined by struct nfst_rec in /usr/include/fs/nfs/nfsrvstate.h and are used represent one of
two things. There are records which indicate that a client successfully acquired state and records that indicate a client's state was
revoked. State revoke records indicate that state information for a client was discarded, due to lease expiry and an otherwise conflicting
open or lock request being made by a different client. These records can be used to determine if clients might have done either of the edge
conditions.
If a client might have done either edge condition or this file is empty or corrupted, the server returns NFSERR_NOGRACE for any reclaim
request from the client.
For correct operation of the server, it must be ensured that the file is written to stable storage by the time a write op with IO_SYNC speci-
fied has returned. This might require hardware level caching to be disabled for a local disk drive that holds the file, or similar.
FILES
/var/db/nfs-stablerestart NFSv4 stable restart file
/var/db/nfs-stablerestart.bak backup copy of the file
SEE ALSO
nfsv4(4), nfsd(8)
BUGS
If the file is empty, the NFSv4 server has no choice but to return NFSERR_NOGRACE for all reclaim requests. Although correct, this is a
highly undesirable occurrence, so the file should not be lost if at all possible. The backup copy of the file is maintained and used by the
nfsd(8) to minimize the risk of this occurring. To move the file, you must edit the nfsd sources and recompile it. This was done to discour-
age accidental relocation of the file.
