2.

Testing SLPR: RAID Manager verifies whether or not the command device can access a target
within SLPR. So, if the command device belongs to SLPR#0, or RAID Manager has no SLPR
function, then the SLPR protection is ignored.

However, if the command device is shared with the port on SLPR#1 and SLPR#2, RAID Manager
allows you to operate the volume on SLPR#1 and SLPR#2.

3.

Rejecting commands: If access is denied on the specified port (or target volume), RAID Manager
rejects the following commands and outputs an error code, EX_ESPERM:

horctakeover

, paircurchk, paircreate, pairsplit, pairresync,

pairvolchk

, pairevtwait, pairsyncwait

raidscan

(except -find verify, -find inst), raidar, pairdisplay

raidvchkset

, raidvchkscan (except -v jnl), raidvchkdsp

[EX_ESPERM] Permission denied with the SLPR
[Cause ] : A specified command device does not have a permission to access other SLPR.
[Action] : Please make the SLPR so that the target port and the command device belongs to the same
SLPR.

SLPR configuration examples

Single host

SLPR configuration on a single host (page 196)

provides an example of when control is denied to

the paircreate and raidscan commands in the following cases:

The volume described on RMINST1 is different from the SLPR of the command device, so the
paircreate

command cannot control the paired volume.

The specified port is different from the SLPR of the command device, so the raidscan -p
CL3-A

command cannot scan any ports that are defined as SLPR#N.

Figure 68 SLPR configuration on a single host

To operate SLPR#N, assign the command device. If RMINST1 has been assigned to a command
device for SLPR#N, the paircreate command is permitted. However, the raidscan -p CL3-A
command (via RMINST0) is unable to scan a port, because the specified port is different than the
SLPR of the command device. In this case, -p CL3-A must be operated via RMINST1, as shown in
the following example.
