I’d to split the screenshots into four quadrants in order for i possibly could show every material from the productivity. Here, i have attempted to trim they all the way down and write precisely the outlines I need to program. To accomplish this, we made use of the soon after order:
This command details all SATP formula and then utilizes grep for all the string’s model, satp_alua, and ---. This causes the production to have line headers and separator contours, which have been the very first two contours inside production. The rest of the productivity series only the outlines with satp_alua inside them. Notice that the -i debate trigger grep to disregard the case.
In this production, observe that the EMC CLARiiON CX household try claimed because of the VMW_SATP_ALUA_CX plug-in, considering fits regarding the design column environment are DGC plus the state choice setting getting tpgs_on.
Having said that, both LSI and IBM 2810-XIV become said by VMW_SATP_ALUA plug-in, considering suits from the provider column, the Model line, together with property value tpgs_on during the Claim choices column.
NetApp can be advertised because of the VMW_SATP_ALUA plug-in, centered on suits regarding supplier line plus the worth of tpgs_on inside the declare selection line merely. In cases like this, the product line wasn’t made use of.
IBM DS8000, which will be model 2107-900 (listed in the production without any dash), and IBM SVC (listed here as unit 2145) were claimed by VMW_SATP_ALUA plug-in, in line with the supplier and product columns only, although the Claim selection column environment just isn’t tpgs_on.
The remaining rule permits VMW_SATP_ALUA to claim products with any merchant or product line price, provided that the state Alternatives column price try tpgs_on. This means any variety maybe not listed in the preceding procedures that comes back a nonzero importance when it comes down to TPGS field into the inquiry responses sequence becomes stated by VMW_SATP_ALUA. You may think of this as a catch-all ALUA claim rule that claims devices on all ALUA arrays that are not explicitly indexed by supplier or design inside the SATP state formula.
Identifying Gadgets’ ALUA Configurations
ALUA configurations become related to LUNs in conjunction with TPGs. To record these configurations, you can easily manage the following order:
An Example from an EMC VNX or CLARiiON CX collection
This result demonstrates the space Array means field set to VMW_SATP_ALUA_CX, which is the just like the VMW_SATP_ALUA plug-in with additional signal to manage specific directions certain to CLARiiON CX ALUA arrays.
The result furthermore demonstrates the space selection kind unit Config range, covered for readability, which include many elements:The basic group of curly brackets, , contains initiator registrationa€“specific configuration. This can be certain to EMC VNX as well as the CLARiiON family of arrays. In this ready, two options are listed:
navireg=on-This ensures that NaviAgent subscription option is allowed on this subject host. It registers the initiator because of the VNX or CX collection if it is not already licensed. Observe that you will need to look at the initiator record regarding array to make certain that Failover Mode is placed to 4, which enables ALUA with this initiator. (you'll find more details on this in part 7.)
ipfilter=on-This solution filters the number’s ip which makes it maybe not visually noticeable to the storing selection. (you will discover more about this in Chapter 7.)
The ALUA AAS control form choices are confined in an additional collection of curly brackets, within that’s another nested pair of curly brackets for TPG’s AAS setting. They are the ALUA AAS management form options:
Explicit_allow=on-This ensures that the number are set up permitting the SATP to exercise its direct ALUA capability in the event the require develops (for example, in the eventuality of a failed control).
