ALTER LU Command
If you are using the SNAX/XF access method, enter the name of the associated
SNAX/XF LU. The name you specify must include the SNAX/XF device name.
The form of the name must be:
$snax/xf-name.#lu-name
A null string (simply enter the attribute keyword without any value) can be specified
to enable the dynamic SNAXFILENAME support. (DYNAMICSUPPORT must also
be set to YES.)
SNAXMAXRETRYCOUNT number
alters the maximum number of times that the SNAX/APC will attempt to open the
access method after an error occurs. The valid values are from 0 through 32767.
The value of zero (0) specifies that no retry will be attempted.
If the specified number of attempts is reached without a successful open of the
SNAX access method, the SNAX/APC LU and its subordinate objects stay in the
STARTING state. SNAX/APC does not attempt to open the SNAX access method
again until a START LU command or a TP-READY verb for that LU is received.
SNAXRETRYTIMER number
alters the amount of time in milliseconds before SNAX/APC attempts to reopen the
SNAX access method after an error occurs. The valid values are -1, and from 1
through 86,400,000(24 hours). The value of -1 specifies that the timer will wait
indefinitely (SNAX/APC will not attempt the retry).
The number can also be specified in the form of (HH:MM:SS.CC), where HH, MM,
SS, and CC represent hours, minutes, seconds, and hundredths of a second
respectively. In addition, both open and close parentheses are required.
This attribute is ignored if the value of SNAXMAXRETRYCOUNT is 0.
DYNAMICSUPPORT {YES|NO}
determines whether the LU supports the dynamic configuration of PTNR-LUs and
PTNR-MODEs. YES specifies that the local LU will support dynamic functions,
NO (the default) specifies that it does not support dynamic functions.
LOCAL-LU-SYNC2-SUPPORT { NONE | SYNCPT }
determines the values of the sync level support indicators (byte 24) in the BIND
request (if SNAX/APC is the primary LU) or in the BIND response (if SNAX/APC
is the secondary LU). NONE indicates that sync level support is not provided by the
local LU; SYNCPT indicates that it is.
Consideration
The ALTER LU command can only be issued successfully when the LU is in the
STOPPED state.
Note. If a small value is specified for SNAXRETRYTIMER and the underlying access method
does not recover from its fault, SNAX/APC may enter a loop temporarily.
